Answer:
The correct option is (d)
domain= real numbers and Range= positive real numbers
Explanation:
The given function is an exponential function in which the condition on the parameters are as follows-
f(x) = a^x
(1) Base condition is , a>0 and a≠1
(2) Domain = The value of x = x can take any value that is x∈ R
(3) Range = f(x)>0 that is f(x) can take positive values only.
