the given expression is
[tex]f(x)=3\times4^x[/tex]
we will check for all four points
by putting their values,
for point A (0,0)
put x = 0
[tex]\begin{gathered} f(x)=3\times4^0 \\ f(x)=3 \end{gathered}[/tex]
for x = 0 we have y or f(x) = 3 so point A(0,0) is not satifying the equation
for point B(1,12)
put x = 1
[tex]\begin{gathered} f(x)=3\times4^1 \\ f(x)=12 \end{gathered}[/tex]
for x = 1 we have y or f(x) = 12
so it is satisfying the equation,
thus the correct answer is option B
