Question
Find the relative extrema of each function, if they exist. List each extremum along with the $x$ -value at which it occurs. Then sketch a graph of the function.$$f(x)=5-x-x^{2}$$
Step 1
The derivative of a function gives us the slope of the function at any given point, and we can use it to find the extrema of the function. The derivative of $f(x)$ is given by: $$f'(x) = -1 - 2x$$ Show more…
