Answer
Explanation:
Step1: Analyze the exponential - function property
The exponential function $e^{x}$ has a range of $(0,+\infty)$, that is $e^{x}>0$ for all real - valued $x$.
Step2: Multiply by 2
Multiply both sides of the inequality $e^{x}>0$ by 2. We get $2e^{x}>0\times2$, so $2e^{x}>0$.
Step3: Subtract 1
Subtract 1 from both sides of the inequality $2e^{x}>0$. We have $2e^{x}-1>0 - 1$, so $2e^{x}-1>-1$.
Answer:
all real numbers greater than -1
