The function f(x)=4(2)^x represents the number of people who share a cat video

The number doubles each hour

Step-by-step explanation: f(x) = 4(2)^2 = 16 and f(x) = 4(2)^3 = 32 and 16 x 2 is 32 if you keep doing this you will see that it is doubling.

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}
