Answer:
(1, 3) can be removed so that the resulting graph represents a function.

Explanation:
A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y.
Here,
X = {-5, -4, -2, 1, 2, 5}
Y = {-4, -3, -2, 1, 2, 3}
Relation from X to Y : {(-5, -3), (-4, -4), (-2, 2), (1, -2), (1, 3), (2, 1), (5, -4)}
This relation is not a function from X to Y because the element 1 in X is related to two different elements, -2 and 3
So, we have to remove either (1, -2) or (1, 3) in order to make this a function.

What is the value of x (x+2)(x-3)=0
wolverine [178]

Answer:

x = 3 or x = -2

Step-by-step explanation:

Solve for x over the real numbers:

(x + 2) (x - 3) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

x - 3 = 0 or x + 2 = 0

Hint: | Look at the first equation: Solve for x.

Add 3 to both sides:

x = 3 or x + 2 = 0

Hint: | Look at the second equation: Solve for x.

Subtract 2 from both sides:

Answer: x = 3 or x = -2
