Use the blue sliders to change the coefficients of the quadratic.
Use the orange slider to move the point.
Note the value of x and the gradient of the tangent, which you can take from its equation.
Try a few different points and see how the gradient varies with x.
Try to establich a rule that connects the x-value and the gradient.
Now try a different quadratic function and repeat.
What is the rule for working out the gradient for a general quadratic function
