Question

Please help.. (y-value = ??)

Answer 1

Answer:   y = 9

====================================================

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.
