Question

If h(x)=6-x, what is the value of (h•h)(10)?
A. -4
B. -2
C. 10
D. 16

Answer 1

For this case we have the following function:

$h (x) = 6-x$

We want to find the value of:

$(h . h) (10)$

We have then:

$(h . h) (10) = h (10) h (10)$

Evaluating the function for x = 10 we have:

$h (10) = 6-10\\h (10) = - 4$

Then, replacing values we have:

$(h . h) (10) = (- 4) (- 4)\\(h . h) (10) = 16$

Answer:

the value of (h • h) (10) is:

$(h . h) (10) = 16$

Option D.
