Sofia used these steps to find the inverse of function Step 1
35 + 4
8
given
Step 2
change /(*) to y
3y + 4
Step 3
switch x and y
Step 4
81 = 3y + 4
multiply each side by 8
Step 5
81 - 4 = 3y
subtract 4 from each side
Step 6
241 - 12 = y
multiply each side by 3
Step 7
24.3 - 12 = 1-10)
replace y with 1-10)
Use this information to complete the statement.
