For each function on [a, b], find every c in (a, b) such that f'(c) equals the secant slope. Show endpoint values, the slope, and the derivative equation.

Customize this worksheetEach supported function is continuous on the closed interval and differentiable inside it. The worked key evaluates both endpoints, forms the secant slope, and solves the exact derivative equation.
Learning objective
Evaluate both endpoints, form the secant slope, solve f'(c) = m, and retain every solution strictly inside the stated interval.
Worked example
c = 1.
The secant slope is (4 - 0)/(2 - 0) = 2. Since f'(x) = 2x, solving 2c = 2 gives c = 1, which lies in (0, 2).
