(1 point) Suppose f(a) = 11 - x2. (a) Find the slope of the tangent line to the graph y = f(x) when x = 1. f(act h) - f(2) Slope = lim = im h (b) Find an equation for the tangent of to the curve y = f(a ) at the point (1, 10). Tangent line: y = (c) On a piece of paper, sketch the curve y = f(a) and the tangent line together
