Question

Show me the steps please? Given f(x)=x^2+6x+8 and g(x)=2x-5... Find: (f+g)(-2). Thanks.

Answer 1

These are functions :)

Answer 2

to find (f+g)(x)
Simply add f(x) and g(x).
That is
(f+g)(x)=x^2+6x+8+2x-5
To find (f+g)(-2)
Put -2 in place of x in (f+g)(x)

Answer 3

Can u do @starshine7?

Answer 4

I'll try, be right back :)

Answer 5

i got -17

Answer 6

(f+g)(x)=x^2+6x+8+2x-5
=x^2+8x+3
(f+g)(-2)=(-2)^2+8(-2)+3
=4-16+3
=7-16
=9

Answer 7

it's -9
