I cant figure this out!

1. Use your calculator to calculate f(-8.80) if f is the function given by the formula f(x) = -0.2x + 2.7

Just sub -8.80 in for x.

Because remember, it's f(x), so f(-8.80), x = -8.80

3. f(x) = -0.2x + 2.7
Find f(-8.8)

Just plug (-8.8) in to the function anywhere there is an "x"

f(-8.8) = -.2(-8.8) + 2.7 = 4.46
