state the domain of the relation.

a) {-4, -3, -2, -1, 0, 2, 5, 8}

b) {-4, -3, -2, -1, 0}

c) {-4, -3, -2, -1}

d) {-4, -1, 2, 5, 8}

Check the picture, notice the domain in red.

recall that the domain is the values for the x-coordinate, whilst the range is the values for the y-coordinate.

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.
