What is the y-intercept?

For these word problems, draw a picture and label everything you know. You'll need to find the vertex first. And remember, parabola's have symmetry!! Don't forget your units.

1

Find the x-value of the vertex. Round up to the nearest whole number.

1

How high above the ground is the tallest point of the arch? (find the y-value of the vertex by plugging in the x-value you found, round up to the nearest whole number)

1

How far apart are the legs of the arch at their bases? (assume the arch starts at (0,0) on the graph and remember SYMMETRY)

1

Find the x-value of the vertex. Round to the nearest whole number.
