Gradient of Tangents
Cubic Function Test
A point and a tangent line is placed on function f
1. Using the selection tool slide the point A to the coordinates (-1,2)
Gradient of Tangent
In the space below enter the value of the gradient at (-1,2)
Instruction
Using the selection tool slide point A along the graph of g in the interval from x=-3 to x=-1. Check the value of the gradient of the tangent while your slide point A.
Rate of change
Indicate what happens to the gradient of g in the interval (-3;-1)
