Nov 9	comment	Prove this function is onto and one-to-one Hi, welcome here.Are you sure your function is $\mathbb R \to \mathbb R$ ? As putting $x= -\frac 12$ contradicts this??
Nov 4	comment	How can I make estimates on large powers and logarithms such as $e^{10}$? your question is unclear IMO. How do you estimate?? One way would be to find power series expansion( exists for exp as well as log) and calculating to whatever accuracy you desire...
