Hello,

Inverses may be a bit complex, But i am here to show you how to do them.

The Inverse of a coordinate is the Y switched to be the X.
For example, say you have the coordinates (1,5) , (5,4), (-3,2), and (4,8 )

They would look like this in a chart
X Y
1 5
5 4
-3 2
4 8

But When we reverse them, the answer will be
X Y
5 1
4 5
2 -3
8 4

This seems pretty simple, right ? it is just the reversing right? But what happens when you have an Equation like this: f(x)=4x+10

Now things get complicated Right ?
Have no fear, I am here to show you how to do this problem!
Click the green Text below to see how I solved f(x)=4x+10.
*PLEASE NOTE: I AM NOT DOING THE STEPS, I AM JUST DOING THE MATH , BUT EVERYTHING IS IN ORDER. IF YOU FOLLOW MY STEPS IN SIMILAR PROBLEMS BUT WITHOUT USING THE SAME NUMBERS, YOU WILL GET THE QUESTION CORRECT.

Answer and How to solve it:

Seems Pretty Simple Now Right ? No ? Why don't you try this problem then. Try to do f(x)=4x+3 On your own! Tell me inside of the comments what your answer is, and how you got it if you still need help!
