Question

Find (fof)(0) f(x)=x^2
a.1
b.0
c.-8
d.-1

Answer 1

Answer:B

f(0)=0

Explanation:

when 0 is squared it’s just 0

Answer 2

Answer: option b.

Explanation:

Given the function f(x):

`f(x)=x^2`

In order to find
`(fof)(x)`, the first thing you must do is to substitute the function f(x) into the same function f(x). Observe the procedure:

`(fof)(x)=(x^2)^2`

Now, you need to simplify:

`(fof)(x)=x^4`

Finally, to find
`(fof)(0)` you need to substitute
`x=0` into
`(fof)(x)=x^4`, then you get:

`(fof)(0)=(0)^4`

`(fof)(0)=0`
