Which of the following equations represents a graph that decreases most rapidly?

a. y=-5x^2-6x-1
b. y=(3/4)x^2-4x-3
c. y=-x^2+13x-36
d. y=3x^2-23x-14

A) y = -5*x^2 - 6*x - 1

Step-by-step explanation:

For this, we need to look at the coefficient that multiplicates the biggest degree in the polynomial (in this case is the coefficient that is in multiplicates the x^2)

If we want the graph that decreases most rapidly, we need to look to the biggest negative number.

The biggest negative coefficient is the -5 in the first option

Then the correct option is A) y = -5*x^2 - 6*x - 1
