    Exponential Functions
    The amount of money spent at West Outlet Mall in Midtown continues to increase. The total T(x) in millions of dollars can be estimated by the function T(x)=12(1.12)^x, where x is the number of years after it opened in 1995. Graph and find the y-intercept.

    Is it 1.12, 12, 1, or 0?

    Thanks!

    Where's your graph? :)

    to find the y intercept, just put x = 0 into the equation.
