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

Hope this helps!
