Question
Find the slope of a line tangent to the curve of each of the given functions for the given values of $x$.$$y=3 x^{3}-9 x \quad(x=1)$$
Step 1
The derivative of a function gives us the slope of the tangent line at any point on the curve. The derivative of $y=3x^{3}-9x$ is found using the power rule for differentiation, which states that the derivative of $x^n$ is $nx^{n-1}$. Show more…
