Hello! I am having some difficulty going about to solve this problem, if anyone can help that would be greatly appreaciated. The question i need help with is number 6.
Thx in advance!
1. Determine the slope of the tangent line by using the derivative.
2. Use the point-slope form of a line to determine an equation for the tangent line. The form I am talking about is $\displaystyle y-y_0 = m(x-x_0)$. You should have values for $\displaystyle y_0$ and $\displaystyle m$.
3. Find the x-intercept of the line. In other words, set $\displaystyle y=0$ and solve for $\displaystyle x$.
