The function f is f of x= √4-x

what is the xcoordinate of the point on the functions graph that is closest to the origin?

  0.5

Step-by-step explanation:

We assume your function is

The distance formula can be used to find the distance from the point on the curve (x, f(x)) to the origin:

  d^2 = (x)^2 + (f(x))^2 = x^2 + (4 -x)

Written in vertex form, this is ...

  d^2 = (x -1/2) + 3.75

This has a minimum at x=1/2, so that is the x-coordinate of the point closest to the origin.
