4th FormGradient of a Curve at a Point
1. The diagram below shows the graph of the function f(x) = x2 2x 3. The tangent to the graph at
(2, -3) is also drawn. Use the graph to determine the gradient of f(x) = x2 2x 3 at x = 2
2. The diagram below shows the graph of the function f(x) = x2 + 2x 3. The tangent to the graph
at (0, -3) is also drawn. Use thegraph to determine the gradient of f(x) = x2 + 2x 3 at (0 , -3)
