What are the extrema of #g(x) = 5x-80?# on the interval #[-1,10]#?
The local extrema are
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.
Maximum: #(10, -30)
