Differentiation: Gradient of a Chord and the Limit as h approaches 0
Find the gradient of each chord (average rate of change), then find the value the chord gradient approaches as h shrinks to 0. This limit is the gradient of the curve, f'(x), at that point.
- 1.For f(x) = 3x^2 - 6x + 6, find the gradient of the chord (average rate of change) between x = -2 and x = 0.
- 2.For f(x) = -3x^2 - 5x + 5, find the gradient of the chord (average rate of change) between x = -1 and x = 2.
- 3.For f(x) = -2x^2 - 5x + 1, find the gradient of the chord (average rate of change) between x = 0 and x = 1.
- 4.For f(x) = 4x^2 + 4x - 2, find the gradient of the chord (average rate of change) between x = 2 and x = 4.
- 5.For f(x) = -4x^2 - 5x + 1, the gradient of the chord from x = 2 to x = 2 + h is calculated for shrinking h below. What value does it approach as h -> 0? (This limit is f'(2).)
- 6.For f(x) = -2x^2 + x + 6, the gradient of the chord from x = -2 to x = -2 + h is calculated for shrinking h below. What value does it approach as h -> 0? (This limit is f'(-2).)
- 7.For f(x) = 4x^2 - 3x + 2, the gradient of the chord from x = 3 to x = 3 + h is calculated for shrinking h below. What value does it approach as h -> 0? (This limit is f'(3).)
- 8.For f(x) = - + 2, the gradient of the chord from x = 3 to x = 3 + h is calculated for shrinking h below. What value does it approach as h -> 0? (This limit is f'(3).)
