Question

The question is .which of the following shows the table representation of the exponential function f(x)=5 times 2^x? I just need a brief explanation with the answer

Answer 1

`f(x)=5(2)^x`

Therefore,

`\begin{gathered} f(x)=5(2)^x \\ x=0,f(x)=5(2)^(^0)=5 \\ x=1,f(x)=5(2)^1=10 \\ x=2,f(x)=5(2)^2=20 \\ x=3,f(x)=5(2)^3=40 \end{gathered}`

The answer is D.
