Answer:

Step-by-step explanation:
We look for where
. The way you find the answer is first, find the point
. Draw a line straight up and down, and see where that line intersects the function. Those intersection points are your answer(there will always be only 1 for a function, but if a graph isn't a function, there might be more than 1).
Using this method here, we see that
intersects our line at
, so
.
