Answer:
y=3/4(4)^x
Step-by-step explanation:
hello :
the graph passes through the point (1,3) : when x=1 and y=3 : 3= ab^1
the graph passes through the point (2,12) : when x=2 and y=12 : 12= ab^2
so the system : ab=3 ...(*)
ab² =12..(**)
ab² = b(ab) = 12 but : ab=3 so : (**) equivalent to b(3)=12 .... b=12/3=4
now : ab= 3 and b=4 so : 4a=3 ... a=3/4
y=3/4(4)^x
The answer should be 10 but it is not in the choices
