Starting high school means following several course expectations at once. Use your actual school schedule to choose a study topic, then practise explaining both a method and the conditions under which it works.
Try the worked exampleRead the situation before using the formula
A formula may accept numbers that a real situation cannot. If an input counts tickets or shirts, fractional and negative inputs may not make sense. State these conditions alongside the calculation, and keep track of the words your teacher uses for each idea.
Which inputs are possible in the situation, and which does the formula allow by itself?
Course ideas for 9th grade.
High-school learning is organized by course. The courses below are examples available for this grade selection, not a required schedule. Follow your school’s course placement and prerequisites.

These examples come from FutureSteps’ Texas starter collection. They introduce selected topics and support review; they are not a complete curriculum, school assessment or course credit.
Choose a domain that fits the situation
Use the meaning of the input to decide which values are allowed.
The domain of a function is its set of allowed inputs. A formula alone may allow values that make no sense in a real situation. Identify what the input measures, then use the situation to limit it.
Counts are usually discrete: they take separate whole-number values. Measurements such as time may be continuous and allow values between whole numbers. Bounds tell you the limits, but you must also state whether fractions are allowed.
A club sells up to 30 shirts for $8 each. Revenue is R = 8n, where n is the number of shirts sold. What are the possible inputs and outputs?
- Identify n as a count of shirts. Zero sales is possible, negative sales are not, and the club sells whole shirts rather than fractions.
- Combine the count restriction with the stock limit: n is a whole number with 0 ≤ n ≤ 30. Writing only the inequality would also allow fractions, so include the whole-number condition.
- Apply R = 8n to these inputs. Revenue can be 0, 8, 16 and so on up to 240 dollars. These outputs form the range; amounts such as 5 dollars are not produced by this model.
Your turn.
A school has 40 tickets to sell for $6 each. If n is the number sold, which domain fits R = 6n?
- All real numbers between 0 and 40
- Whole numbers from 0 through 40
- All positive numbers, with no upper limit
Show the answer and explanation
Whole numbers from 0 through 40
Tickets are counted in whole numbers, including zero, and at most 40 can be sold. The domain is , 1, 2, …, 40; fractions and negative values do not fit.

A routine to try next.
- Choose one topic from a current course and write the exact question you need to answer.
- Identify the meaning and restrictions of each variable before calculating.
- Save a short explanation of the restriction, then try a different example without looking back.
These public guides and examples are free to read without an account. FutureSteps accounts are for ages 13 and older, with email verification and applicable permission steps. Younger learners can explore these public examples with a grown-up.
Eligible students receive a 90-day homework trial from their signup date, after email verification and required age and permission checks. No invitation is needed. Up to 100 Study requests per day, subject to your weekly allowance and service availability. Longer chats and photos may use more allowance. AI coaching requires a paid upgrade from the start. The homework trial needs no card and never charges automatically.
Grade level does not determine account eligibility. For eligible students, in-app Study includes AI homework help and tutoring; college and career AI coaching is a separate paid feature.
Questions before you begin.
Are these the required courses for every ninth grader?
No. These are examples of available starter courses, not a prescribed ninth-grade schedule. Course order varies by school and placement. Choose the course you are actually taking, including a different math or English level when appropriate.
How does the in-app learning path build on these examples?
Eligible students choose a supported state, grade and courses. Lessons include explanations, worked examples and quick checks. Students can save Notes, mark their own progress and ask Study about a lesson when they have access. Progress labels reflect the student's selections, not a school grade or a mastery assessment.
