Answer:
- domain: all real numbers
- range: all positive real numbers
Step-by-step explanation:
The function is defined for all values of x, so the domain is all real numbers.
An exponential function has a horizontal asymptote at y=0. Multiplying it by 4 doesn't change that. The value cannot be zero, and it cannot be negative. The range is all positive real numbers.
You have to do 7 x 4 because a square has four sides
