Respuesta :
Assuming they mean straight line, then this graph is one-to-one. It is impossible to draw a horizontal line that will cross through more than one point on the diagonal line already graphed.
Contrast this with a parabola where it is possible to draw a horizontal line through more than one point on the parabola. So the parabola would not be one-to-one.

Answer:
It is given that line intersects y axis at (0,5).
If written in the form of function
f(x)=5
Means , every element in preimage has image equal to 5.
A function is said to be one one , if every element in preimage has distinct image.
Here,each and every element in Preimage has image equal to 5.
So,the given function is not one-to-one.
