Question

If h(x) = 3x − 1 and j(x) = −2x, find h[j(2)].

11

−11

13

−13

Answer 1

First thing you want to do is find the value of the function j(x) at x=2
Tell me what you get

Answer 2

2?

Answer 3

the function is j(x)=-2x, so plug in 2 for x

Answer 4

-4

Answer 5

perfect. Now you have h(j(2)), where j(2)=-4, so h(-4).

Answer 6

use the same process you used above, but with the function h(x)=3x-1 at x=-4

Answer 7

did you get an answer?

Answer 8

-11?

Answer 9

close, make sure you keep track of your - signs

Answer 10

so just 11

Answer 11

h(-4)=3(-4)-1

Answer 12

=-12-1

Answer 13

-13 oops

Answer 14

there ya go, you got it!

Answer 15

thank you!!
