Answer:
The domain of exponential functions is all real numbers. The range is all real numbers greater than zero. The line y = 0 is a horizontal asymptote for all exponential functions. When a > 1: as x increases, the exponential function increases, and as x decreases, the function decreases.
Answer:
x > 4
Step-by-step explanation:
27 < 5 ( x ) + 7
27 < 5x + 7
20 < 5x
4 < x
x > 4
Answer:
x=-1
Step-by-step explanation:
-2x - 5 = -3
