Answer: vertex (-1, 0) axis of symmetry -> x = -1
Step-by-step explanation:
f(x) =
to find the vertex do
x+1 = 0
to find the x value
x = -1
plug -1 into the equation
f(-1) =
f(-1) = 3(0)
f(-1) = 0
Therefore, the vertex is (-1, 0)
The axis of symmetry is
x = -1
because that is where the lowest x value is
This picture is too blurry for me to see the actual problem, but it looks like subtracting fractions, you just subtract the numerator (top number) from the other numbers' numerator, and the denominator stays the same, example:
6/8-2/8=4/8
If your teacher wants it in simplest form you just duvide the numerator and denominator by he same number, example
4/8 divided by 4/4=1/2
Answer:
D+0.21
Step-by-step explanation:
Answer: At x = 2200 level of production, it will get maximum revenue.
Step-by-step explanation:
Since we have given that
p = 55-0.0125x
and Revenue function is given by
We will take the first derivative of it.
Now,we will find the critical points :
and R''(x)=-0.025<0, so it will get maximum revenue.
Hence, At x = 2200 level of production, it will get maximum revenue.
