x^2+(y-2)^2=4\implies y=2\pm\sqrt{4-x^2}

describes a circle of radius 2 centered at (0,2). A revolution of this region about the y-axis would give you a sphere of radius 2, so the volume would be \dfrac43\pi\times2^3=\dfrac{32}3\pi.

-x^2+4x-8 <br>axis of symmerty​
V125BC [204]

Answer:

\boxed {\boxed {\sf x=2}}

Step-by-step explanation:

The axis of symmetry can be calculated using the formula:

x=\frac{-b}{2a}

First we must determine a and b from the quadratic: -x^2+4x-8. This is in standard form, with the highest power first in descending order.

Standard form is also: ax^2+bx+c

If we compare this to the quadratic given, we can conclude that:

a= -1 \\b= 4 \\c= -8

Substitute the values for a and b into the formula.

x= \frac{-(4)}{2(-1)}

Multiply in the denominator.

x=\frac {-4}{-2}

Divide.

x=2

This can also be determined from the graph. It is the x-coordinate of the vertex or the maximum/minimum. It divides the quadratic into 2 symmetrical halves.
