Question 19 please! help quick!!

f-¹(x) = [4(3 - 2x)]/15 .

Step-by-step explanation:

f(x) = y = [3(4 - 5x)]/8

f-¹(x) is given as;

x = [3(4 - 5y)]/8

multiplying both sides by 8 gives;

8x = 3(4 - 5y)

8x = 12 - 15y

15y = 12 - 8x

Dividing both sides by 15 gives

y = [4(3 - 2x)]/15

hence f-¹(x) = [4(3 - 2x)]/15

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.

can you rephrase the question ? it is unclear : -)
