Question

Which equation best represents the graph shown below?

Answer 1

Answer:

f(x) = x^2 - 2

Step-by-step explanation:

This looks like a parabola with the vertex at  (0, -2)

It also goes through points (1, -1) and (-1, -1)

The equation:   f(x) = a (x - h)^2 + k

f(x) = a x^2 - 2

we see   f(1) = -1 =  a (1)^2 - 2 ,

-1  = a - 2,  a = 1

so  f(x) = x^2 - 2

Answer 2

Answer:

x to the power of 2 equals 3

Step-by-step explanation:

because
