Question
Find the equation of the tangent to the graph of $y=3 x^{2}-x$ at $x=1$
Step 1
The derivative of a function gives us the slope of the tangent line at any point. Using the power rule, the derivative of $3x^{2}$ is $6x$ and the derivative of $-x$ is $-1$. So, the derivative of the function is $y'=6x-1$. Show more…
