If f x equals x -3 + g x equals 1 - x 2 - 9 find ( f og) (x and give any restrictions on its domain

evablogger [386]

$\begin{gathered} f(x)=x-3 \\ g(x)=\frac{1}{x^2-9} \\ (\text{fog)(x)}=\frac{1}{x^2-9}-3 \end{gathered}$

the denominator cannot be zero, because the division by zero is not defined, therefore:

$\begin{gathered} x^2-9=0 \\ \text{Solving for x:} \\ x^2=9 \\ \sqrt[]{x^2}=\sqrt[]{9} \\ x=\pm3 \end{gathered}$

Therefore the domain of (f o g)(x) is:

$D\colon(-\infty,-3)\cup(-3,3)\cup(3,\infty)$

PLEASE HELP! NO LINKS! TEN POINTS!<br><br> please explain it if you can!

I think the answer would be 112cm.

To find the area of the triangle you need to do basexheight divided by 2.
8x10 divided by 2 = 40

To find the area of the rectangle
12x6=72

40+72= 112cm

I’m not sure if it’s right but I hope this helps.
