Question

I can't math.

Find the number of x-intercepts of the graph of the function: y = 4x^2 + 4x + 1

Answer 1

X is equal to 1/2 or 0.5

Answer 2

There is only one x intercept: x = -0.5 or -1/2

Explanation:

To find the x-intercepts of the graph of the function, we need to find the values of x where y = 0. In other words, we need to solve the equation 4x^2 + 4x + 1 = 0 for x.

4x^2 + 4x + 1 = 0

(2x+1)^2 = 0

2x + 1 = 0

2x = 0 -1

x = -1/2
