D.
4.8

Answer 1

Everywhere you see an x, replace it with -3. Then evaluate

Answer 2

f(x) = 0.6(3 – x)

f(-3) = 0.6(3 – (-3))

f(-3) = ???

Answer 4

\(f(\color{red}x) = 0.6 (3-\color{red}x) \\ f(\color{red}{-3}) = 0.6 (3-(\color{red}{-3}))\)

Answer 5

you just replace x to whether what x was replaced to in f(x)

Answer 6

So you simply replace x to -3, then solve it.

Answer 7

So I got C 3.6

Answer 8

right!
