Question

this one is confusing @Nory

Answer 1

Let's talk about stretching.
We discussed shifting, and stretching is when you multiply the equation by a certain factor.

Answer 2

Remember when you were learning about lines and slope, and if you had a line with slope 3 it was steeper than a line of slope 1?

Answer 3

It's kind of the same idea here. You're stretching the parabola by a factor of 2, so you multiply the equation by 2.
Does that make sense?

Answer 4

still confused;/

Answer 5

Remember when you learned about slope? If you want a line twice as steep, you just multiply the slope by 2, right?

Answer 6

x2^2?

Answer 7

That looks right, I think...except you would write it as 2x^2. Is that what you meant?

Answer 8

yea sorry but thank you

Answer 9

No problem. :) You're doing well.
