Using technology, we determined that mary’s investment account can be modeled by the function, m(x) = 3.03(2.18)^x in thousands of dollars. what was mary’s initial investment?
$3.03
$4.96
$3,030
$4,960

Initial investment can be calculated by setting the value of x to zero since it is an initial value where time is zero. Using the given model, we calculate as follows:

M(x) = 3.03(2.18)^x
M(0) = 3.03 (2.18)^0
M(0) = 3.03 <FIRST OPTION
