# Extremum, Increase and Decrease sections – Extremum to an exponential function in a closed interval – Exercise 6911

### Exercise

Determine the absolute extrema for the following function

$$f(x)=2^x$$

On the closed interval

$$[-1,5]$$

$$\max_{[-1,5]}f(x)=32$$
$$\min_{[-1,5]}f(x)=\frac{1}{2}$$
