Answer:
Step-by-step explanation:
so f-1(x) means we are finding the inverse
f(x) = 3x - 7.....change f(x) to y
y = 3x - 7.....now switch ur x and y and solve for y
x = 3y - 7....add 7 to both sides
x + 7 = 3y...divide both sides by 3
(x/3) + 7/3 = y....rearrange
y = (x/3) + 7/3....can also be written as : y = 1/3x + 7
now just change ur y to f-1(x)
f-1(x) = x/3 + 7/3.....or f-1(x) = 1/3x + 7/3
