Question

Find the equation of tangent to the curve y= x^2-1. X-2 where the curve cut the x axis

Answer 1

The curve cuts the x axis at points with co-ordinates (2,0);(1,0).

So now differentiate the equation as you know it’s a polynomial function hence it’s differentiable...

Differentiating it you will find the slope of the tangent at those points..which are..

slope,m=7 for (2,0).

m= -3 for (1,0).

So you can now write the equations knowing the poinrs and slopes of the corresponding lines.
