The value, V, of a certain investment doubles in every month, m. Which function can be used to find the value of the investment at the end of m months if there is an initial value of $0.25?
V=0.25(m)2
cap v is equal to 0 point 2 5 times m squared

V=0.25(2)m
cap v is equal to 0 point 2 5 times 2 to the m th power

V=025(x)2m
cap v is equal to 025 times x raised to the 2 m power

V=2(0.25)m
