Question

5. Evaluate f(x) = 2x – 7 at the given value. f(4)=?

Answer 1

f(5) = 14

Explanation:

Just replace the variable "x" with "5":

f(5) = 2×5 + 4 = 14

Answer 2

1

Explanation:

Since the value of x is 4 ( because four is in the position of x) you would plug in 4 into he equation.

2(4) = 8

Then 8 - 7 = 1

F(4) is 1

Therefore, your final answer is 1.
