Question

Last question ughhh

Answer 1

g(x) is just the expression within the square root symbol

Answer 2

3x-4?

Answer 3

good

Answer 4

f(x) is just what is being applied to g(x), which is just taking the square root

Answer 5

so f(x) = sqrt(x)

Answer 6

by defining f(x) and g(x) this way, we are making f(g(x)) = sqrt(3x-4)

Answer 7

for part I do I put the sqrt symbol or just 3x-4

Answer 8

no square root symbol just 3x - 4

Answer 9

okay

Answer 10

so for part II

Answer 11

Answer 12

that's II

Answer 13

so f(x)=sqrt(x) is II

Answer 14

yes

Answer 15

soo for part III you are just verifying that f(g(x)) = sqrt(3x-4)

so you would just start with f(x) = sqrt(x) and then substitute g(x) for x inside f(x)

Answer 16

wait g(x) is 3x-4 right

Answer 17

yes

Answer 18

f(3x-4)=sqrt(3x-4)

Answer 19

awesome, so you have completed the verification. to answer this question you would just show your work for: f(x) = sqrt(x) and then f(g(x)) = sqrt(g(x)) = sqrt(3x-4)

Answer 20

well they are only asking for the verification right?

Answer 21

yes

Answer 22

so I don't have to put the solved part

Answer 23

well, you would still have to show your work

Answer 24

"verify" means they want you to show that the original statement is true using your own calculations/reasoning/etc.

Answer 25

Right, I understand what you're saying

Answer 28
