Answer:
False.
Step-by-step explanation:
The exponential function
f(x)=ax, where a>0 and a≠1, has a range that depends on the value of a. If a>1, the function's range is all positive real numbers. If 0<a<1, the range is all positive real numbers less than 1. In either case, the range does not include negative numbers or zero.
However, when a=1, the function f(x)=x is a linear function, not an exponential function. The range of this linear function is indeed all real numbers since it continues indefinitely in both directions on the real number line. Therefore, the statement is true only when considering the function f(x)=x (a linear function), not when considering exponential functions.
