Question

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

Answer 1

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, <u>all</u> exponential functions look basically the same. Just draw a typical curve, then label the axes appropriately.
