Option #1:

f(4), this means that x = 4
To find f(4), substitute/plug in 4 into "x" in the function:
Plug in 4 into "x" since x = 4


f(4) = 2
Option #2:

f(4), this means that x = 4
To find f(4), substitute/plug in 4 into "x" in the function:

Answer:

Step-by-step explanation:
the volume of a cylinder is given by:

and the volume of a cone is given by:

since both have the same height and radius, we can solve each equation for
(because this quantity is the same in both figures) and then match the expressions we find:
from the cylinder's volume formula:

and from the cone's volume formula:

matching the two previous expressions:

we solve for the volume of a cone
:

substituting the value of the cylinder's volume
