Sketch the parabolas

To determine

**To sketch:**

The parabolas y = x^{2} and y = x^{2} - 2x + 2 and check if there is a line that is tangent to both curves.

Explanation

**Calculation:**

Consider the curve Â

By differentiating, the slopeÂ of tangent at x is

The second curve is

Let

and tangent to

This gives us following equations

From the first equation weâ€™ve
