Four equivalent forms of a quadratic function are given. Which form displays the y-intercept of the function?

f (x) = 3 (x2 + 2x - 48)

f (x) = 3 (x + 1) 2 - 147

f (x) = 3x2 + 6x - 144

f (x) = 3 (X + 8) (x-6)

f (x) = 3x2 + 6x - 144

Step-by-step explanation:

The y intercept is the value of the function when x = 0

We want the easiest way to see when x=0

We want a constant term after all multiplication is done. The constant term is the y intercept

f (x) = 3x2 + 6x - 144 has a constant term
