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

Answer:
An equation could be 2-4= -2
Step-by-step explanation:
You would count down 4 times from the the number 2 (below the line that says 3) then your answer would be -2 since below it, is -3. Obviously the number obove it would be 2.
Answer:
x = -13
Step-by-step explanation:
Given that:
9-2x=35
Adding 2x-35 on both sides we get:
9 - 35 = 2x
-26x = 2x
Dividing both sides by 2
-13 = x
