Given:
[tex]\begin{gathered} f\mleft(x\mright)=100\times3^x \\ g\mleft(x\mright)=100\times\mleft(3.5\mright)^x \\ h\mleft(x\mright)=100\times4^x \end{gathered}[/tex]To find the function which has the least and most quickly grows:
Since 3 < 3.5 < 4.
So, the function that has the most quickly grows is,
[tex]h(x)=100\times4^x[/tex]So, the function that has the least quickly grows is,
[tex]f(x)=100\times3^x[/tex]
