Question

The graph of f(x) = (2.5)x and its reflection across the x-axis, g(x), are shown. What is the range of g(x)? all real numbers all real numbers less than 0 all real numbers greater than 0 all real numbers less than or equal to 0

Answer 1

we given function is

f(x)=(2.5)x

we know that domain of given function f(x) is range of g(x)

as we can see that domain of f(x) is all real numbers

hence range of g(x) is all real numbers.

option (a) all real numbers is correct option
