These are "composite" functions.
g(x+a)  means insert (x+a) into g(x) to replace every x:
g(x+a) - g(x) = -5(x+a)^2 +4(x+a) +5x^2 - 4x
 = -5(x^2 + 2ax + a^2) +4x +4a + 5x^2 - 4x
Now just Multiply and sum up the answer.

A cone has a volume of 5 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?
Pie

Answer:

15 in^{3}

Step-by-step explanation:

Given:

Volume of Cone= 5 inch ^{3}

Solution:

Formula:

Volume of Cone =\frac{1}{3} \pi r^{2} h

Volume of Cylinder= \pi r^{2} h

\therefore We can say that

Volume of Cone = \frac{1}{3} \times Volume of Cylinder

\therefore Volume of cylinder = 3 \times Volume of Cone

Now Substituting given data we get

Volume of Cylinder= 3\times5

Volume of Cylinder= 15 in^3
