Question
Sketch the graphs of the following functions for $x > 0$.$$y=\frac{12}{x}+3 x+1$$
Step 1
The derivative of a function gives us the slope of the tangent line at any point, which is useful for finding local maximum and minimum points. The derivative of $y$ with respect to $x$ is given by: $$y'=-\frac{12}{x^2}+3.$$ Show more…
