What causes the graph of the parent function x squared to become a thinner parabola

Step-by-step explanation:

The vertex form of a parabola is y = a(x-h)^2 + k.

The variable a is our stretch factor, so the larger a is, the skinnier the parabola, and the closer to zero a is, the fatter.

Look at the attachment. The wider parabola has a factor of 1/4, and the skinnier one has a factor of 2.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
