Square roots & rational equations

Desmos throws out the extraneous answers automatically.

5

How many solutions

Count where the curve hits the x-axis.

6

Vertex, max, or min

Click the peak. Done.

7

Parameter problems (sliders)

"For what value of k…" becomes a drag.

8

Regression (tables of values)

Let Desmos fit the curve and read the coefficients.
