what is the range of the function y = 4e^x?\no all real numbers greater than 0\no all real numbers less than…

Explanation:

Step1: Recall the property of exponential function

The exponential function $e^x$ has the property that for all real - valued $x$, $e^x>0$.

Step2: Analyze the given function

Given $y = 4e^x$. Since $e^x>0$ for all real $x$, when we multiply both sides of the inequality by 4 (a positive number), the direction of the inequality remains the same. So $4e^x>0$.

Answer:

all real numbers greater than 0
