Question

Dylan looked at the function .and said, "This function is always greater than 0, so 0 is the absolute minimum." Explain why Dylan is incorrect.

Answer 1

Given data:

The given function is f(x)=4(1/2)^x.

The given function always greater than zero, the given function never become equal to zero, the asymptote at y=0.

Thus, zero can't be consider as the absolute minima of the function.
