Question
Find the slope of the tangent line to each curve when $x$ has the given value. Do not use a calculator.$$f(x)=x^{2}+5 ; x=2$$
Step 1
The derivative of a function gives us the slope of the tangent line at any point. The derivative of $x^{2}$ is $2x$ and the derivative of a constant is zero. So, the derivative of $f(x)$ is $f'(x) = 2x$. Show more…
