Question
1. Find (f+g)(x) if f(x) = -3x²+2x-3 and g(x) = 2x² - 3x +4.
O (f+g)(x) = -5x² + 5x - 7
O (f+g)(x) = 5x² - 5x+7
O (f+g)(x) = -x²-x+1
O (f+g)(x) = x²+x-1
Transcribed Image Text:1. Find (f+g)(x) if f(x) = -3x²+2x-3 and g(x) = 2x² - 3x +4. O (f+g)(x) = -5x² + 5x - 7 O (f+g)(x) = 5x² - 5x+7 O (f+g)(x) = -x²-x+1 O (f+g)(x) = x²+x-1
Expert Solution
Step 1

We have given functions

fx=-3x2+2x-3

gx=2x2-3x+4

So, 

f+gx=fx+gx

f+gx=-3x2+2x-3+2x2-3x+4

 

f+gx=-x2-x+1
