If the tangent line y = f(x) at (3,3) passes through the point (7,19) then f '(3) would be 4.
Is this correct?
Can you check this one as well, please?
Find an equation of the tangent line to the parabola y = 6x^2 - 7x at the point (5,115). Leave your equation in solved for y form.
I differentiated and input x to get my slope, and ended up with y = 53x - 150. Is this correct?
