Question

A little help here? Inverse?
F(x) = 7x + 2

Answer 1

So far i have:
F(x) = 7x + 2
Y = 7x + 2
X = 7y + 2
Sqrtx = sqrt7y + 2

Answer 2

Where are you not getting??

Answer 3

I do not know where to go from here.

Answer 4

Why are you taking square root in last step everywhere??

Answer 5

y=7x+2
x=7y+2
7y=x-2
y=(x-2)/7
Answer: y=(x-2)/7

Answer 6

See, when you flip x and y, after that very equation, you need to find y in terms of x..

Answer 7

After you get x=7y+2, you just solve for y in terms of x.

Answer 8

Your first three steps are okay, don't do last step if you have linear function..

Answer 9

Thats is the way they taught me @waterineyes.
And that makes alot of sense @Idealist10 ! Thank you!

Answer 10

They?? Who??

Answer 11

You're welcome!

Answer 12

Answer 13

No much how many of them you are trying to solve, if you are solving questions of only one type, then I suggest you to do only 2 problems of that type..
