What is the range of the function y=2e^x-1
all real numbers less than –1
all real numbers greater than –1
all real numbers less than 1
all real numbers greater than 1

B. All real numbers greater than –1.

Step-by-step explanation:

We have been given a function . We are asked to find the range of our given function.  

We know that the range of an exponential function is .

Upon looking at our given function, we can see that , therefore, the range of our given function would be that is all real numbers greater than .

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
