Substitution Method is used for solving equations in 2 Variables, where you find the value of one variable in terms of the other and then substitute that value into any one of the equations. It can also be used when one Variable is known to you and you have to find the other.

Need answers to the ones that i haven’t written anything for

Trava [24]

Answer:

domain - (-infinity,infinity)

range - (-infinity, 2]

axis of sym - x=-1

y int - (0,-1)

at what value (row 1) - (-1,2)

Step-by-step explanation:

domain is side to side, it never ends bc of the arrows

range is top to bottom, there is no bottom bc of the arrow, but it has a top at 2 (the value on the y axis)

the axis of sym is basically the line that runs through the vertex, it's where you could fold it in half and it would still match up
