Answer
(f o g) (-1) = -10
Explanation
f(x) = 3x - 1
g(x) = x² - 4
We should note that (f o g) means that we try to work out f(x), but we will now replace the x with g(x)
(f o g) = f[g(x)]
(f o g) = 3[g(x)] - 1
= 3(x² - 4) - 1
= 3x² - 12 - 1
= 3x² - 13
And (f o g) (-1) means we substitute -1 for x in the simplified expression.
(f o g) (-1) = 3(-1)² - 13 = 3(1) - 13 = 3 - 13 = -10
Hope this Helps!!!
