Answer:
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.
Answer: first one (-4,1) and the second is (0,1)
Step-by-step explanation:
Explanation:
If you make a vertical line test, this graph is the only one that doesn't have two points in the same line. Unlike the other graph's who have the same domain and there would be more than one point in the vertical line test.
