A student recognizes that given the function f(x), they are able to simplify the function as follows: 2²-3x - 4 x+1 (x + 1)(x-4) x+1 =x-4 From this the student decides that since the slope of the resulting line is 1, they conclude that f'(-1)= 1. Explain the error in this conclusion. it.

A student recognizes that given the function f(x), they are able to simplify the function
as follows:
f(x) =
x²-3x - 4
x+1
(x + 1)(x-4)
x + 1
=x-4
From this the student decides that since the slope of the resulting line is 1, they conclude
that f'(-1) = 1. Explain the error in this conclusion.
