Answer: y = 9</h3>
====================================================
Explanation:
Locate 12 on the horizontal x axis number line.
Then move straight up until reaching the parabola.
Afterward, move to the left to arrive at y = 9 on the vertical y axis.
We predict the y value will be y = 9 for the input of x = 12.
Refer to the diagram below to see what's going on.
