# EVALUATE THE FUNCTION WITH INDICATED INDEPENDENT VARIABLE WORKSHEET

Evaluate the function at the given value of the independent variable and simplify.

Problem 1 :

When f(x) = x2 - 5 evaluate f(x - 4)

Solution

Problem 2 :

When p(a) = -4a - 2; Find p(2a)

Solution

Problem 3 :

When f(x) = 2x - 4; Find f(x + 3)

Solution

Problem 4 :

When h(n) = 2n - 4; Find h(1 + n)

Solution

Problem 5 :

When f(x) = 4x - 5; Find f(2 + x)

Solution

Problem 6 :

When g(x) = 3x - 2; Find g(2x)

Solution

Problem 7 :

When h(n) = n + 1; Find h(n + 2)

Solution

Problem 8 :

When f(x) = 4x + 4; Find f(3x)

Solution

Problem 9 :

When f(x) = -x - 1; Find f(x2)

Solution

1)  f(x - 4) = x2 - 8x + 11

2)  p(2a) = -8a - 2

3)  f(x + 3) = 2x + 2

4)  h(1 + n) = 2n - 2

5)  f(2 + x) = 4x + 3

6)  g(2x) = 6x - 2

7)  h(n + 2) = n + 3

8)  f(3x) = 12x + 4

9)  f(x2) = -x2 - 1

Find the value(s) of x given that:

Problem 1 :

f(x) = 3x2 - 2x + 5 and f(x) = 5

Solution

Problem 2 :

f(x) = x2 - x - 5 and f(x) = 1

Solution

Problem 3 :

f(x) = -2x2 - 13x + 3 and f(x) = -4

Solution

Problem 4 :

f(x) = 2x2 - 12x + 1 and f(x) = -17

Solution

1)  So, the values of x are 0 and 2/3.

2)  So, the values of x are -2 and 3.

3)  So, the values of x are -7 and -1/2.

4)  So, the value of x is 3.
