Which of the following relations represent a function? {(-1,-,,7)} {(-3,,-,7)} {(-1,,,5)} {(-1,,,7)}

{(-1,4), (2,7), (3,7)} is a function

Step-by-step explanation:

For something to be a function, any given x must have one and only one y

{(-1,-3), (3,2), (3,7)}

-1(x) only has -3(y)

3(x) has 2(y) and 7(y), making it not a function

{(-3,7), (3,-7), (3,7)}

-3(x) only has 7(y)

3(x) has -7(y) and -7(y, making it not a function

{(-1,4), (-1,7), (3,5)}

3(x) only has 5(y)

-1(x) has 4(y) and 7(y), making it not a function

{(-1,4), (2,7), (3,7)}

-1(x) only has 4(y)

2(x) only has 7(y)

3(x) only has 7(y)

This is a function

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
