Q:
# This set of points is on the graph of a function.{(−3, 9), (−1, 1), (0, 0), (2, 4)}Which points are on the graph of the inverse?Select each correct answer.(0, 0)(1, −1)(−9, 3)(4, 2)What is the inverse of f(x)=−3x+5 ?f−1(x)=13x−53f−1(x)=3x−5f−1(x)=−3x+5f−1(x)=−13x+53

Accepted Solution

A:

1. (0, 0)

2. f(x) = −3x+5

f(x) = y, switch the x and y

x = -3y+5, now solve for y:

-3y +5-5 = x-5

-3y = x-5

-3y/-3 = (x-5)/-3

y = -x/3 + 5/3

Dunno why that's not an option
