Question

If f(x)=−2x−2, g(x)=−3x²+7x- 4, and h(x)=−8x²+ 6, find f(2).

a) 0
b) -6
c) -10
d) -14

Answer 1

Substitute x with 2 in the function f(x) = -2x - 2 to find f(2), which calculates to -6.

Step-by-step explanation:

To find f(2) for the function f(x) = -2x - 2, we substitute the value of x with 2.

The calculation is as follows:

• f(2) = -2(2) - 2
• f(2) = -4 - 2
• f(2) = -6

Therefore, the answer is b) -6.
