- 1.Given the function f(x) = 3x - 5, determine the inverse function f^-1(x) and state the domain and range of both the original function and its inverse.
- 2.A quadratic function is defined by g(x) = -2x² + 8x + 10. Find the zeros of the function and determine the coordinates of the vertex (maximum point).
- 3.A ball is thrown into the air. Its height in meters at time t seconds is modeled by h(t) = -5t² + 20t + 1. Calculate the maximum height reached by the ball and the time at which it hits the ground (set h(t) = 0).

- 5.A population of bacteria grows according to the function P(t) = 500 * (1.2)^t, where t is time in hours. If the population is currently 500, how many bacteria will there be after 5 hours? Round your answer to the nearest whole number.
- 6.Given the function h(x) = √(x - 2) + 3, determine the domain and range. Explain why the domain must be restricted to x >= 2.

What Your Child Will Learn
Grade 11 functions formalizes function notation and asks students to think about relationships more abstractly than in previous years. Students learn to determine domain and range from equations, graphs, and real-world contexts, evaluate functions using f(x) notation, and perform operations on functions including composition and finding inverse functions algebraically and graphically.
Quadratic functions are revisited with more depth, including solving quadratic inequalities, working with the discriminant to characterize roots, and analyzing transformations more formally as mappings of points. Students also study rational and radical functions at an introductory level, identifying restrictions on the domain caused by division by zero or negative values under a square root.
Throughout the course, students are expected to move fluidly between algebraic, graphical, numerical, and verbal representations of the same function — a flexibility that becomes essential in the exponential, sequences, and trigonometric strands that follow within the same course. This unit essentially teaches students to think about math in terms of functions rather than isolated equations, a shift that underpins all subsequent senior-level math.
Skills Covered
- Evaluating and interpreting function notation f(x)
- Determining domain and range from equations and graphs
- Finding and verifying inverse functions
- Composing two functions and simplifying the result
- Solving quadratic inequalities
- Identifying restrictions on rational and radical functions
Curriculum Aligned: Foundational strand of Grade 11 Functions (MCR3U, with related content in the college-prep MCF3M), establishing function concepts used throughout senior math.
Parent Tip: Function notation like f(x) can look like a foreign language even to parents who were comfortable with algebra — it helps to remember it's just relabelled 'y'. Asking your teen to translate a line of f(x) notation into a plain-English sentence ('this means: plug 3 into the function and see what comes out') is a good comprehension check you can do without touching the math yourself.
What your child will practice

Check my workFrequently Asked Questions
How often should my child practice functions?
Short daily practice sessions of 10-15 minutes are more effective than long weekly sessions. Consistency builds lasting understanding.
How do I know if my child is at the right level for these worksheets?
If your child can complete about 70% of the problems correctly, the level is appropriate. If it's too easy or too hard, try an adjacent grade level.
Can I use these worksheets for homeschool?
Yes. The worksheets align with standard curriculum expectations and can supplement any math program. Generate multiple worksheets to create a full practice set.
