If h(x)=6-x, what is the value of (h•h)(10)?
a. -4
b. -2
c. 10
d. 16

For this case we have the following function:

We want to find the value of:

We have then:

Evaluating the function for x = 10 we have:

Then, replacing values we have:

the value of (h • h) (10) is:

Option D.

the answer is 15% decrease
