Answer:
I like saying rise over run because it helps me remember that rise means how many units you move up or down from point to point which on a graph would be a change in the y values. Also that run means how far left or right you move from point to point which on the graph would mean a change of x values.

vlada-n [284]
The discriminant of the function is 120, and the function has 2 different x-intercepts
<h3>How to determine the discriminant?</h3>
The function is given as:
f(x) = -7x^2 + 8x + 2
The discriminant (d) is calculated using:
D =b^2 - 4ac
So, we have:
D = 8^2 - 4 * (-7) * 2
Evaluate
D = 120
Because the value of D is greater than 0, then the function has 2 different x-intercepts

Answer:
A = $ 5137.65 .
Step-by-step explanation:
Amount = $3000
interest rate = 9 %
= 9/12 = 0.75%
compounded monthly for
time = 6 years.
= 6 × 12 = 72 months.
A = $ 5137.65
hence, the amount after compounding $3000 at the rate of 9% after 6 years is A = $ 5137.65 .
