The graph of y=(3x-x)^.5 is a semi-circle with diameter coincident with the positive x-axis, radius 1.5, center at (1.5,0). create a function passing through (3.5,5) and intersecting the x-axis at x=2 and x=5.

. . All this is all true . . . but who needs it ??
Create a function passing through (3.5, 5) and intersecting the x-axis at x=2 and x=5.
We can see that a parabola will work.Code:|
| (3½,5)
| *

- - + - * - - - * - -
| 2 5
From the two x-intercepts, we have: .
To pass through, we have: .
. .
Therefore: .
