Question

How to evaluate g(2)+g(3) if g(x)=2x^2

Answer 1

g(2) + g(3) = 26

Explanation:

to evaluate g(2) , substitute x = 2 into g(x)

g(x) = 2x² , then

g(2) = 2(2)² = 2(4) = 8

similarly for g(3)

g(x) = 2x² , then

g(3) = 2(3)² = 2(9) = 18

Then adding the 2 results

g(2) + g(3) = 8 + 18 = 26
