Answer:
f(x) = - 8
Explanation:
The given function is
f(x) =2x^2 -4x -6
The first step is to find the derivative of the function. Recall, if
y = ax^b
y' = abx^(b - 1)
Thus,
f'(x) = 4x - 4
We would equate f'(x) to zero and solve for x. We have
4x - 4 = 0
4x = 4
x = 4/4
x = 1
We would substitute x = 1 into the original function and solve for f(x) or y. It becomes
f(1) =2(1)^2 -4(1) - 6 = 2 - 4 - 6
f(1) = - 8
Thus, the minimum value is f(x) = - 8

Darn I had one of those a few weeks ago, I'm so sorry if I'm wrong but I think it's option 3? I'd wait for someone else to answer though just it case I'm wrong. God bless!
Answer:
One of them is the root
im not sure about the other one: I'd just call it the value of x

Answer:
Slope = 0
Step-by-step explanation:
Let's use the equation 
for this problem.
We have two points: (2,0) and (-2, 0)
Let's plug them both into the equation shown above.
Solve.
0 - 0 = 0
-2 - 2 = -4
= 
= 0
A zero in the numerator means this equation has a slope of 0.
Any line with a slope of 0 is a horizontal line.
Slope (rate of change) = 0
