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

<u><em>Answer:</em></u>
<em>You haven't attached a picture but this is what your line should look like
</em>
<em>
</em>
<em>Step-by-step explanation:
</em>
<em>
</em>
<em>For this equation you simply have to graph it.
</em>
<em>
</em>
<em>First, you have to remember that these equations follow a formula: y=mx+b. m is the slope of you line and b is the y-intercept.
</em>
<em>
</em>
<em>Next, you need to graph it. First, graph your b, in this case 2. You would go up 2 on you graph (graph (0,2)). Then, you would graph your slope which is 3.
</em>
<em>
</em>
<em>Now, remember that slope equals y/x, so think of the number 3 being like 3/1. You would start at (0,2) and go up 3 points in the graph, then over 1 point (graph where you end up). You repeat that from each new point you make until you have enough points to create a straight line.

2b -1 = 11
⇔ 2b = 12
⇔ b = 6

Answer:
88cm^3
Step-by-step explanation:
The volume of a pyramid is the base times height divided by 3. First, we can find the area of the base. We have a right triangle with a base of 8 and a height of 6. The area of a triangle is the base times height divided by 2. This gives us:
8 * 6 ÷ 2 = 24cm^2
We can see that 11cm is the height as it is perpendicular to the base. We can set up an expression from the formula mentioned at the beginning:
11 * 24 ÷ 3 = 88cm^3
