Identify the domain and range of the following relation.

left-brace left-parenthesis 3 comma 7 right-parenthesis comma left-parenthesis 3 comma 8 right-parenthesis comma left-parenthesis 3 comma negative 2 right-parenthesis comma left-parenthesis 3 comma 4 right-parenthesis comma left-parenthesis 3 comma 1 right-parenthesis right-brace

Domain = {3}, Range = {-2,1,4, 7, 8}

Step-by-step explanation:

Given relation is

R = {(3,7), (3,8), (3,-2), (3,4), (3,1)}

We need to find the domain and range of the following relation.

If a relation is defined as

then the domain is the set of x-values and range is the set of y-values.

Domain of the given relation is

Domain = {3}

Range of the given relation is

Range = {-2,1,4, 7, 8}

step-by-step explanation:

0

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
