Question

For the function f(x) = 3 − 8x, identify the values of f(0), f(1/2), and f(−2).

3; 7; −13
−5; −1; −13
3; −1; 19
−5; 7; 19

Answer 1

The answer is 3: -1: 19

Explanation:

I. f(x) is output x is input so

If x = 0

f(0) = 3 - 8(0)

f(0) = 3

If x = 1/2

f(1/2) = 3 - 8(1/2)

= 3 - 4

f(1/2) = -1

If x = -2

f(-2) = 3 - 8(-2)

= 3 - (-16)

= 3 + 16

f(-2) = 19

Hope that help :D
