Given that \(f(x) = \left(\dfrac{1}{\pi}\right)^x\), what is the range of f(x) on the interval \([0, \infty)\)? Give your answer in interval notation.

Note that when x = 0....f(x)  =   1

 

As x grows larger and larger.....f(x)   tends to approach y =  0   (the x axis)

 

So....the range is   (0, 1]
