Question

I'm a little rusty with my functions.How do we approach this piecewise function?

Answer 1

Answer:

f(-4) = -10

Explanations:

In the piecewise function given:

f(x) = 2x - 2 when x < -1

Since - 4 < -1. the function f(x) = 2x - 2 will be used to calculate f(-4)

f(-4) = 2(-4) - 2

f(-4) = -8 - 2

f(-4) = -10
