Question

Please help me with this 1 question, its worth alot and I want to get it correct!

The graph of y = x2 is shown below. Using complete sentences, explain how the graph of y = 2(x + 3)2 - 4 would differ from this parabola?

Answer 1

Let's do this in a step-by-step fashion.

Answer 2

We know what the graph of \(f(x)=x^2\) looks like:\[\]

Answer 3

If we multiply it by two, that is, \(f(x)=2x^2\), the graph will get "thinner:"\[\]
