Identify the vertex and the axis of symmetry of the graph of the function y = 3(x + 2)2 – 3. A. vertex: (2, –3);
axis of symmetry: x = 2
B. vertex: (–2, –3);
axis of symmetry: x = –2
C. vertex: (2, 3);
axis of symmetry: x = 2
D. vertex: (–2, 3);
axis of symmetry: x = –2

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

answer4 to the second power is 16

and 4 to the third power is 64,
