2) Find the slope of the tangetn line to the graph at given point and give an equation of the tangent line

f(x)=3/2x at (1, 3/2)

3)Let f(x)=x^2+6x

a) Find the derivative f' of f

b) Find the point on the graph of f where the tangent line to the curve is horizontal

hint: find the value of x for which f'(x) =0

I'm having problems with derivatives, can anyone teach me how to do these problems step by step! I appreciate it!
