Question

Can someone please help me
The functions of F and G are defined as follows
f(x)=-3x^2-2 and g(x)=-4x-3
find f(3) and g(2)
simplify the answer as much as possible

Answer 1

so I know I do
F(x) = -3x^2-2
F(3)=-3(3)^2-2(3)
but im stuck after that what do i do now

Answer 2

from there you simplify using order of operations. exponents → multiplication → subtraction

Answer 3

where'd the second 3 come from in f(3)?

Answer 4

so F(3)=-27-6 ?????

Answer 5

sorry im really bad at math

Answer 6

YOur original was f(x) = -3x² - 2, so f(3) = -3(3)² - 2.
I think it should be f(3) = -27 - 2

Answer 7

im so cofused lol how would i solve F(3)=-27-2 than ??

Answer 8

-29 wouldnt be the answer would it ?

Answer 9

yes. so it's -29.
I was just saying that there shouldn't be an extra 3 at the end because there was no x there.

Answer 10

okay thank you so than for g(x)=-4x-3
it would be
g(2)=-4(2)-3
g(2)=-8-3
so than the answer would be -11 ?????

Answer 11

yes

Answer 12

thank you

Answer 13

you're welcome
