Question

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

Answer 1

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: `(-1,-85)`
Maximum: #(10, -30)
