# What are the extrema of g(x) = 5x-80? on the interval [-1,10]?

Apr 26, 2018

The local extrema are $x = - 1$ and $x = 10$

#### Explanation:

The extrema of a function can be found where the first derivative is equal to zero. In this case the function is a line, so the end points of the function in the designated range are the extrema, and the derivative is the slope of the line.

Minimum: $\left(- 1 , - 85\right)$
Maximum: #(10, -30)
