Question

How many x -intercepts does the parabola whose function is f(x)=3 x 2 +4x+4

Answer 1

They are none x- intercepts on the parabola. To find the x-intercept, substitute in 0 for y and solve for x.

Answer 2

The answer is 0

Explanation:

Let's break this down. . .

x-intercepts are x-intercepts that have 0 as their y.

For example: (9,0) , (5,0), (3,0) are x-intercept, while (0,9), (0,5), (0,3) are not x-intercepts.

Graph f(x) = 3x^2 + 4x + 4

There is no x-intercept.
