Answer
Option B is correct.
(f + g)(x) = 3x² - 6
Step-by-step explanation
f(x) = 2x² + 1
g(x) = x² - 7
We are now told to evaluate (f + g)(x)
Note that (f + g)(x) represents the sum of the 2 functions f(x) and g(x)
Hence,
(f + g)(x) = f(x) + g(x)
= (2x² + 1) + (x² - 7)
= 2x² + 1 + x² - 7
= 2x² + x² + 1 - 7
= 3x² - 6
Option B is correct.
(f + g)(x) = 3x² - 6
Hope this Helps!!!
