Question

Here is a graph that represents y=x2.1. Use the sketchpad to sketch a graph thatrepresents: y= (x – 6)2 + 10.2. How do you know that you have graphed theequation correctly?

Answer 1

ok

I'll graph it

We must move the vertex 6 positions to the right, and then 10 positions up.

The original equation is the green one

The blue parabola is the one after the changes.

The equation of the new parabola is:

`\text{ y = -(x + 2)}^2\text{ - 10}`
