Which of the following is a true statement about functions? A. If fand g are functions, then (tog)(x)=(g f)(x) . B. If fand g are functions, then (f + g)(x) = (g + f)(x) If fand g are functions, then (f - g)(x) = (g - f)(x) D. If fis a function , then (f(x + 2))/(g(x)) = (g(x))/(f(x + 2))

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

=240
