Question

Which statements describe the graph of y = 4x2 + 28x + 49? Check all that apply. The graph has two x-intercepts because 4x2 + 28x + 49 has two different factors. The equation 2x + 7 = 0 can be used to find a zero of the function. The equation (2x – 7)2 = 0 can be used to find the y-intercept. The graph has a double root at x = StartFraction negative 7 Over 2 EndFraction. The graph intersects the y-axis at y = 49.

Answer 1

The equation 2x+7=0 can be used to find a zero of the function. The graph intersects the y-axis at 49

Explanation:

The other statements are not correct because since (2x+7)^2 gives the polynomial function y=4x^2 +28x + 49, there are "two" answers, but it is the sa,e answer of -7/2. The graph also does not have a double root at -7/2, that is the x-intercept

Answer 2

b,d, and ,e
