Question

Find the minimum value of the parabola y =X^2 + 5x – 3

Answer 1

Minimum value = −13/4

Explanation:

Answer 2

-37/4

Explanation:

The minimum value of the parabola y =x² + 5x – 3 is f(-b/2a)

in this case a = 1 and b = 5 and c = -3

then

-b/2a = -5/2(1) = -5/2

then

f(-b/2a) = f(-5/2) = -37/4
