The graph is that of y = 2x2 - 5x - 3. For what value of x will y be negative? For what value of x will y be negative?

The graph is that of y = 2x2 - 5x - 3. For what value of x will y be negative? For what value of x will y be negative?

A.

-\(\frac{1}{2} \leq x\) < 3

B.

-\(\frac{1}{2} < x \leq 3\)

C.

-\(\frac{1}{2} < x < 3\)

D.

-\(\frac{1}{2} \leq x \leq 3\)

Correct answer is C

2x2 - 5x - 3 = 0

2x2 - 6x + x - 3 = 0

2x(x - 3) + 1(x - 3) = 0

(2x + 1)(x - 3) = 0

2x + 1 = 0

2x = -1

x = -\(\frac{1}{2}\)

x - 3 = 0

-\(\frac{1}{2}\) < x < 3
