Answer:
c
Step-by-step explanation:
yes
Answer:
B
Step-by-step explanation:
You can solve this by using the vertical line test. When you do the vertical line test, the vertical line should only pass through one point on the function. That means that there can to be only one value of x for every y. Set B is the only set where the x value doesn't repeat.
Equal to, I think. Hope this helps.... If not sorry.
Answer:

Step-by-step explanation:
A way to find the inverse function is to swap the x and y (f(x)) in the equation.

We can check that it is an inverse function by using a property of inverse functions:

If we plug in the f(x) function into the variable x of the inverse function, we should end up with x

It checks out!
