Graph the function f(x) = 5(0.21)x.

I assume you are working with an exponential function

f(x) = 5 * 0.21^x

All functions y = a^x go through the point (0,1)
so, clearly, yours must go through (0,5)
Now, when x=1, y = 5*0.21 = 1.05

Having reviewed the topic in your text, or online, you should now be able to sketch the curve. Just to make things easy, all exponential functions look basically the same. Just draw a typical curve, then label the axes appropriately.
