Grade 11 Function Evaluation Worksheet

Read each question carefully and follow the instructions to evaluate the functions. Show all your work.

1. Given the function f(x) = 3x - 5, find f(4).

2. If g(x) = x² + 2x - 1, determine g(-3).

3. In the expression f(x) = 2x + 7, 'f' represents the   and 'x' represents the  .

4. If h(t) = t³ - 2, then h(a) =  .

5. For the function k(x) = |x - 5|, what is k(2)?

6. Evaluate the piecewise function f(x) for the given values: f(x) = { 2x + 1, if x < 0 x² - 3, if x ≥ 0 } a) f(-2) b) f(0) c) f(3)

a) f(-2) =

b) f(0) =

c) f(3) =

7. If f(x) = x - 10, then f(10) = 0.

8. For the function f(x) = √x, f(-4) is a real number.

9. Given f(x) = x² + 3 and g(x) = 2x - 1, find f(g(x)).
