Question

The factored form of a quadratic equation is y=(2x+1)(x-5), and the standard form is y=2x²-9x-5. Which of the following statements accurately describes the graph of y?

A) The x-intercepts are -1 and 5, and the y-intercept is -5.
B) The x-intercepts are -1/2 and 5, and the y-intercept is -5.
C) The x-intercepts are -1/2 and 5, and the y-intercept is 5.
D) The x-intercepts are 1 and -5, and the y-intercept is -5.

Answer 1

Answer:

B.

Step-by-step explanation:

To find the x intercepts solve for x:

(2x + 1)(x - 5) = 0

x = -1/2 ,  5.

Y-intercept is obtained by  putting x = 0:

y = 2(0)^2 - 9(0)  - 5 = -5.
