Answer:
Step-by-step explanation:
f(x) = 2x + 3.....change f(x) to y
y = 2x + 3.....switch the x and y and solve for y
x = 2y + 3
(x - 3) = 2y
(x - 3) / 2 = y or y = 1/2x - 3/2 <===
can be written as : f-1(x) = (x - 3) / 2....f-1(x) is the inverse
Answer:
C. 24
Step-by-step explanation:
We should find how many miles Jory travels in 15 minutes first.
45 ÷ 15 = 3
