Which of the following functions i which of the following functions are one to one? select all that apply there are 3 answers

The function is one-to-one function ⇒ 1st

The function is one-to-one function ⇒ 2nd

The function is one-to-one function ⇒ 4th

Step-by-step explanation:

* Lets explain how to solve this problem

- One to one function is the function that has no reputation in the value

 of the y-coordinates for every corresponding x-coordinates

- That means when you draw a horizontal line at any value of y, then

  the horizontal line intersects the graph of the function at one point

  only

- So to solve the problem look to the attached figures

# The red graph of the function ⇒1st graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at only one point

- Take care there is a horizontal asymptote at y= 1/3, that means

  there is no value of x at y = 1/3

∴ The function is one-to-one function

# The blue graph of the function ⇒2nd graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at only one point

∴ The function is one-to-one function

# The green graph of the function ⇒3rd graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at only one point

∴ The function is one-to-one function

# The purple graph of the function ⇒5th graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at more than one point

∴ The function is not one-to-one function

# The black graph of the function ⇒4th graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at more than one point

∴ The function is not one-to-one function

* The answers are 1st , 2nd and 4th functions
