Answer:

{ - 1, 0, 7 }

Step-by-step explanation:

Substitute the values of x from the domain into the relation to obtain the corresponding values of y , that is the range

x = - 1 : y = 3(- 1)² + 4(- 1) = 3(1) - 4 = 3 - 4 = - 1

x = 0 ; y = 3(0)² + 4(0) = 0 + 0 = 0

x = 1 : y = 3(1)² + 4(1) = 3 + 4 = 7

range is { - 1, 0, 7 }

2x+2y=10 solve for x
irakobra [83]

Isolate the x. Note the equal sign. What you do to one side you do to the other.


Subtract 2y from both sides


2x + 2y (-2y) = 10 (-2y)


2x = 10 - 2y


Isolate the x, divide 2 from both sides and from all terms.


(2x)/2 = (10 - 2y)/2


x = 5 - y


Place the variable in the front


x = -y + 5


x = -y + 5 is your answer


hope this helps
