Question

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

Answer 1

it's A. Y=-5x^2-6x-1

i chose the other answer and got it wrong and it showed this was the right answer. So hope this helps

Explanation:

Answer 2

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

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
