Question
Find an equation of the tangent line to the curve at thegiven point.$y=x^{4}+2 x^{2}-x, \quad(1,2)$
Step 1
The derivative of $y=x^{4}+2 x^{2}-x$ is obtained using the power rule for differentiation, which states that the derivative of $x^n$ is $n*x^{n-1}$. So, the derivative of $y=x^{4}+2 x^{2}-x$ is $y'=4x^{3}+4x-1$. Show more…
