Is the relation a function? select yes or no for each relation.

Answers:

a. Not a function

b. Function

c. Not a function

d. Function

Explanation:

For a relation to be called a function, each x-value MUST be associated with ONLY ONE y-value

If any x-value has more than one y-value, then the relation is not a function

Now, let's apply this to the given relation:

1- Relation A:

(3,3) , (3,-2) , (-2,4) and (1,-6)

We can note that x=3 has two different y-values. Therefore, this relation is not a function

2- Relation B:

(3,3) , (5,-2) , (-2,4) and (1,-2)

We can note that each x-value is associated with only one y-value. Therefore, this relation is a function

3- Relation C:

(3,3) , (5,-2) , (-2,4) and (5,9)

We can note that x=5 has two different y-values. Therefore, this relation is not a function

4- Relation D:

(3,3) , (5,-2) , (-2,4) and (4,9)

We can note that each x-value is associated with only one y-value. Therefore, this relation is a function

Hope this helps :)

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

f(x) = y

f(-3) = -5
