The domain of the function can be all real numbers and the range is y less than zero y < 0 option (D) is correct.
What is an exponential function?
A relation of the form y = a×, with the independent variable x ranging over the entire real number line as the exponent of a positive number a.
Given that:
An exponential function on a coordinate plane proceed toward y=0 lying in the 2nd quadrant bends up and increases toward quadrant 1.So, As x inclines to -∞ ,y inclines to 0 but not equals to it.
Let f(x) be a exponential function:
f(x) = a×
Here a is the constant
x is the domain of the function.
As x inclines to = +∞,y inclines to +∞.
Thus, the domain of the function can be all real numbers and the range is y less than zero y< 0 option (D) is correct.
