Question

If h(x) =6 -x, what is the value of (h•h)(10)

Answer 1

Answer:

Your exact value should be 10h$^{2}$

Step-by-step explanation:

I put it into the calculator and that's what came out.

Answer 2

Answer:  16

Step-by-step explanation:

The given function : $h(x) =6 -x$

Then, the composition function of $(h\cdot h)(x)=h(x)\times h(x)$

$\\\\\Rightarrow\ (h\cdot h)(x)=(6-x)(6-x)=(6-x)^2$

Using identity $(a-b)^2=a^2-2ab+b^2$, we have

$(6-x)^2=6^2-(2)(6)(x)+x^2\\\\\Rightarrow\ (h\cdot h)(x)=(6-x)^2=36-12x+x^2$

Now, $(h\cdot h)(10)=36-12(10)+(10)^2$

$=36-120+100=16$

Hence, the value of $(h\cdot h)(10)=16$
