ok so for this question, just take a derivative. Then you get f'(x)=-3x^2. Now plug in x=0 cause that's the point in question. Then you get f'(x) = 0. So now we know that the tangent slope must be 0. So the equation of the tangetn line has the form y=mx+b or y=b since m=0. Now to find b, plug the point in question again. I don't see any x in y=b, but I do see a y. Plug y = 1. Then b=1. So tangent line is y=1
