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

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
