what is this parametric graphing?

no idea

lol, i don't know if they mean to parametrize y=3^x 
with a variable say t

but I'm exactly sure here lol

im not sure i mean *

jim_thompson5910 · Answer

To parameterize (not even sure that's a word?) the function y = f(x), let x = t

so 

y = f(x)
y = 3^x
y = 3^t

so the parametric form of f(x) is 

x = t
y = 3^t

taken together, they help draw this graph

jim_thompson5910 · Answer

with parametric equations, it's very easy to graph the inverse. Simply swap the roles of x and y

so now 

x = 3^t
y = t

graphing, using a calc like TI83, you'll get this graph
