Question

A quadratic equation is written in four equivalent forms below.

Answer 1

Answer: III. y = x^2 - 2x - 48

The y intercept are the points on the graph where the curve hits the y-axis, so it’s the point where x=0
With the equation y=x^2 - 2x - 48 we can easily plug in 0 for x and see that the when x is zero, y is -48.
