Question

Find the inverse of the function.

f(x) = 7x + 2

Answer 1

if you want i cant teach how to deal with is and you will do it by yourself @olivya999

Answer 2

f-1(x) = quantity x plus two divided by seven
Not a one-to-one function
f-1(x) = quantity x minus two divided by seven
f-1(x) = x divided by seven minus two

Answer 3

okay

Answer 4

f(x)=7x+2 and y=7x+2 is the same f(x)=y

Answer 5

then you switch places y goes to x and x goes to y : you will have x=7y+2

Answer 6

f(x) = 7x + 2
replace f(x)(basically y) with x
x=7y+2
so solve to get y alone

Answer 7

then you try to have y seperated, here it is y=(x-2)/7

Answer 8

so c?

Answer 9

yep

Answer 10
