SOLUTION: f(x) = 3x Find f(2) The x is the exponent of 3. So I have y = B of x. right? 2 = 3x and this is where i get lost. Thanks Chris

You can put this solution on YOUR website!
if x is exponent then you copied it wrong....learn how to do proper notation in the applet where you submit the problem. it's 3 to the power of x, so 3%5Ex
f%282%29=3%5E2=9
