Question

PLEASE HELP - PLEASE SHOW WORK Given the following functions, find each of the values: f(x)=x^2−7x+6 g(x)=x−1 (f+g)(−5)= ______ (f−g)(4)= ______

Answer 1

• (f+g)(-5) = 60
• (f-g)(4) = -9

Explanation:

These are the values we will need:

f(-5) = (-5)^2 -7(-5) +6 = 25 +35 +6 = 66

f(4) = 4^2 -7(4) +6 = 16 -28 +6 = -6

g(-5) = -5 -1 = -6

g(4) = 4 -1 = 3

__

(f+g)(-5) = f(-5) +g(-5) = 66 +(-6)

(f+g)(-5) = 60

__

(f-g)(4) = f(4) -g(4) = -6 -3

(f-g)(4) = -9
