f(x)=−7x 2 +8x+2f, left parenthesis, x, right parenthesis, equals, minus, 7, x, squared, plus, 8, x, plus, 2 What is the value o
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

Slope: - 3/4
Step-by-step explanation:
Place your pencil on point y= 4. Go up 3 spaces, then, 4 to the left to the next point.
Slope = - 3/4
( a line going up hill: positive slope. A line going downhill: negative slope)
