Question

given f(x) = 3 - 4x

Answer 1

What are you trying to find? The derivative?

Answer 2

use the equation to fil in a graph

Answer 3

Plug in all the x values into the function and that is you f(x) value

Answer 4

f(-6) = 3 - 4(-6)
= 27
f(-3) = 3 - 4(-3)
= 15
f(0) = 3 - 4(0)
= 3
f(1) = 3 - 4(1)
= -1

Answer 5

And for the last part set f(x) = to -5

3 - 4x = -5

And solve for the x value

Answer 6

Do you understand my approach?
