(a) Is f'(x) greater at point A or at point B? Explain.
f'(x) is greater at point A. The slope of the tangent line is positive at A.
f'(x) is greater at point A. The slope of the tangent line is negative at A.
f'(x) is greater at point B. The slope of the tangent line is positive at B.
f'(x) is greater at point B. The slope of the tangent line is negative at B.
(b) Estimate f'(x) at point B.
