\fIf m) = 4:32 4m + 7, find f'(5).' Use this to find the equation of the tangent line to the parabola y = 4:1:2 4m + 7 at the point (5, 87). The equation of this tangent line can be written in the form :1; = ms: + b where m is: ' ' and where bis: ' ' If f ( t) = (t2 + 5t + 8) ( 2+2 + 4), find f'(t). Find f'(3)
