The exponential equation given is,
[tex]f(x)=kb^x[/tex]
Given the points
[tex](0,3)\text{ and (2,12)}[/tex]
Therefore, the values for k and b will be resolved graphically.
Let us now plot the graph using a graphical calculator
From the graph,
[tex]\begin{gathered} y_1=f(x) \\ a=k=3 \\ b=2 \end{gathered}[/tex]
Final answers
[tex]\begin{gathered} k=3 \\ b=2 \end{gathered}[/tex]
