Question

Given the function f(x) = 5(x+4) − 6, solve for the inverse function when x = 19.

Answer 1

@hartnn

Answer 2

ok, you could find inverse function and then plug in x=19
other shorter way is to set
5(x+4) − 6 = 19
and find 'x'
both answer will be same

Answer 3

can you find x from
5(x+4) − 6 = 19
?

Answer 4

do I distribute the 5 first?

Answer 5

add the '6' on both sides

Answer 6

you can distribute the 5 first too, no problem

Answer 7

so x=1?

Answer 8

yes!

Answer 9

correct, good :)

Answer 10

the inverse function when x = 19. is = 1

Answer 11

Thank you so much!
