we know that
Range of a function is the values that a function can take in its domain
The range interval of a function is between the minimum value and the maximum value that the function can take
so
in this problem
The range of the function is the interval-------> [1, ∞)
That means
The minimum value of the function in the domain is [tex] 1 [/tex]
The maximum value of the function in the domain is infinite
