a)

When you evaluate f(0) just plug in 0 in for every x.

b)

When you evaluate f(5) just plug in 0 in for every x.

c)

When you evaluate f(-2) just plug in 0 in for every x.

Given:

Find: (a) f(0), (b) f(5), and (c) f(-2)
.
All this problem require you to do is assign values to x and solve for the given function.
.
In (a) f(0) means go to the given function and substitute 0 for every x you find. When you
do that the function is:
.
and this simplifies it to which reduces to:
.

.
In (b) f(5) means go to the given function and replace all the x's in it with 5. When you do
it becomes: which reduces to:
.
so that
.
In (c) which becomes and this
simplifies to
.
Hope this helps you to understand the problem.
