Question

lim---->0 4.5^(2x)-2.25/4.5^x-1.5

Answer 1

replace x by zero, see what you get

Answer 2

I did that but the answer wasnt right.

Answer 3

i get
\[\frac{1-2.25}{1-1.5}=\frac{1.25}{.5}=2.5\] does that look right?

Answer 4

yeah. I figured you had to use a number a little more than zero.
I had tried 0.1 but I didnt go far enough. thank you
