...Let

(a)Find the point(s) on the graph ofwhere the slope of the tangent line is equal to 0.f

set f'(x) = 0 , solve for x, determine the function value(s) for each value of x

(b)Find the equation of the tangent line to the graph of f(x) at the point where x=0.

you need two things ... the point of tangency (0, f(0)) on the curve and the slope at that point, f'(0)

y - f(0) = f'(0)(x - 0)

what method do I use to solve these problems and how do I solve them?
