The graphs below have the same shape. what is the equation o the red graph?

So the equation of the red graph is already given to us: . I assume you meant the blue graph?

We can use the vertex form: , where is the vertex. (We can ignore because is 1 for this graph.) Remember that the vertex is the maximum or minimum of a parabola and the point that the line of symmetry passes through. For f(x) the vertex is (0,0).

The vertex for is at on the coordinate plane. (4 left, 2 down)

Plug into the vertex form:

The double negative becomes a positive, and then you're done:

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

-2 is the right
