FAN FOR ANSWER! Which of the following exponential functions goes through the points (1, 12) and (2, 36)? f(x) = 4(3)−x f(x) = 3(4)−x f(x) = 3(4)x f(x) = 4(3)x

plug in f(x) = 12 and x = 1 and see if they fit do the same for f(x) = 36 and x = 2

4(3) - x = 4^3 - x or 4^(3-x) ?

3(4)x could mean 3^4x or 3(4)^x !!!

Oh ok but which one is it! lol how about another question?

For example I'm not the greatest at math so how would I come across that answer?
