QuestionFind the secant line equation for $y=f(x)=x^{2}+x$ at $x=-3$ and $x=-1$, and the tangent line at $x=-3$. Which slope formula is correct?

Studdy Solution
The equation of the tangent line is therefore $y = -x -1$.
The solution to the problem isa. The equation of the secant line is $y = -x -$. b. The equation of the tangent line is $y = -x -1$.
