Solving Quadratic Equations: Zero Product Property
Question 86853 • Algebra III A
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 = .The graph intersects the y-axis at y = 49.
Answer
A
The graph has two x-intercepts because 4x2 + 28x + 49 has two different factors.
B
The equation 2x + 7 = 0 can be used to find a zero of the function.
C
The equation (2x – 7)2 = 0 can be used to find the y-intercept.
