Question

How many x-intercepts are there in y = –3x2 + 4x + 4

Answer 1

You can factor it to find the answer:

–3x^2 + 4x + 4 
–(3x^2 - 4x - 4)
–(3x + 2)(x - 2)

x=-2/3 or 2, which means that there are  x intercepts, at -2/3 and 2.

Answer 2

Y = -3x^2 + 4x + 4

Educated guess: There may be about 2 x - intercepts in the equation.
