Question

g(f(h(-3)))
f(x)= 2x
g(x)= -3x+4
h(x)= 2x-8
can someone please give me the answer?.. ive been stuck for days on this and I really need help..

Answer 1

what is the value of h(-3) ?

Answer 2

I don't know... hmm.. that's just the problem all typed out word for word :(

Answer 3

when we look at h(x) it is defined for values of x

when x = -3, what does h equal?

Answer 4

-3.. right?

Answer 5

h= 2x-8, when x = -3, id say it is -6-8

Answer 6

so then what do I do with -6-8? or would that be the answer?

Answer 7

this is a process, we are asked to find an overall solution, but we have to pick it apart.

Answer 8

g(f(h(-3)))

find h(-3)

find f(h(-3))

then we can determine g(f(h(-3)))

Answer 9

h = 2x - 8, when x=-3, h=-6-8

f = 2x, when x = -6-8, what is f?

g = -3x+4, what is g when x=f?

Answer 10

f=-12x-16x?

Answer 11

no, -6-8 = -14

f = 2x, when x=-14
f = 2(-14)

Answer 12

so then -3x+4(-28x)
-84x-112x= 196x^2?

Answer 13

g = -3x+4, what is g when x=f=-28

g = -3(-28) + 4

Answer 14

so then the answer would be.. -80!?

Answer 15

84 + 4, your basic math skills need alot of work :)

Answer 16

hahha I know!! this has been so hard for me.. so the final answer is 88..
