Question

"If f(x) = -2 - 3 and g(x) = x^2 + 5x, find each value."
Problem: g(-3)

If someone could answer and somehow explain how they figured it out that'd be great!

Answer 1

g(x) = x^2 + 5x

g(-3) = (-3)^2 + 5(-3) ... replace EVERY copy of x with -3

g(-3) = ???

Answer 2

Tell me what you get

Answer 3

g=8 ?

Answer 4

incorrect

Answer 5

Oh i see what I did wrong, is the answer 24?

Answer 6

what is (-3)^2 equal to?

Answer 7

9

Answer 8

5(-3) is equal to ???

Answer 9

It equals 15

Answer 10

no, but close

Answer 11

Oooh -15 then?

Answer 12

so that means

g(-3) = (-3)^2 + 5(-3)

g(-3) = 9 + (-15)

g(-3) = -6

Answer 13

OH I always mess up the negatives, thanks a bunch @jim_thompson5910
