Here are two logarithmic function graphing questions. They just seem to easy for some reason which makes me suspicious. Also I am unsure about the notation I have used. The question asks to state the Domain, Range, values of intercepts, and equations of asymptotes that exist.
Thank you for your help

Question #1 \(\displaystyle f(x)= - \log _2 (x + 2) + 3\)
My answers:
\(\displaystyle domain\left\{ {x \in R|x \ge - 2} \right\}\)
Range All real numbers
X intecept =-1.87
Y intecept= 4
equation of Asymptote x=-2
Question #2 \(\displaystyle g(x) = 2e^x - 2\)
My answer:
Domain =all real numbers
\(\displaystyle range\left\{ {x \in R|y \le 5} \right\}\)
X intercept = 0
Y Intercept = 0
Equation of Asymptote y=-2
