Find the function of the form $\displaystyle f(x) = Ca^x$. In the graph, m = 3 and q = 27.
m is the x-intercept and q is a point on the graph (-1, 27)
So what is $\displaystyle f(x)$?
there is no need for all this weird formating. it only serves to confuse people. do you mean
$\displaystyle f(x) = CAx$ where $\displaystyle C$ and $\displaystyle A$ are constants?
note that the x-intercept is the x-value when y = 0, so that
$\displaystyle CAm = 0$ ...........................(1)
also, $\displaystyle (-1,27)$ means, when x = -1, y = 27, so that
$\displaystyle CA(-1) = 27$ ..........................(2)
there seems to be some info missing, because this system is inconsistent
