Answer:
3x² - 2x - 6
Step-by-step explanation:
We are given that:
f (x) = 3x² - 2
g (x) = 2x + 4
We want to find the value of (f - g)(x), this means that we will simply subtract g (x) from f (x) as follows:
(f - g)(x) = f (x) - g (x)
(f - g)(x) = 3x² - 2 - (2x + 4)
(f - g)(x) = 3x² - 2 - 2x - 4
(f - g)(x) = 3x² - 2x - 6
Hope this helps :)
