Question

which of the following statements is true about f(X)=-2(3)^X
it has a y-intercept at(0,-2)
it has a y-intercept at (0,3)
its graph is a line
its graph is a parabola

mathmate · Answer

Hint:
Exponential functions of the form :  $f(x)=a (b^x)$ has a y-intercept equal to a, since $b^0=1$.

Try to construct a table of values and plot the function (unless you have a TI-83).
First determine the type of function you are working with, then solve the problem, ok?
