Can a line be drawn in the plane that is not a function?
Ο Νο
O Yes

if you can draw any vertical line that intersects more than one point on the relationship, then it is not a function.

Step-by-step explanation:So it is a no ok.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
