Answer:
the equation of the axis of symmetry is 
Step-by-step explanation:
Recall that the equation of the axis of symmetry for a parabola with vertical branches like this one, is an equation of a vertical line that passes through the very vertex of the parabola and divides it into its two symmetric branches. Such vertical line would have therefore an expression of the form:
, being that constant the very x-coordinate of the vertex.
So we use for that the fact that the x position of the vertex of a parabola of the general form:
, is given by:

which in our case becomes:

Then, the equation of the axis of symmetry for this parabola is:

Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
Starting with 2x+6=22
You subtract 6 from each side of the equation:
2x=16
You want to isolate the "x" so you divide each side by 2.
x = 8
check your answer: 2x + 6 = 22
2(8) + 6 = 22
16 + 6 = 22
Hey there!
I'm going to set up the equation slightly different.

The range of the following relation R {(3, −2), (1, 2), (−1, −4), (−1, 2)} is Your answer: {−1, 1, 3} {−1, −1, 1, 3} {−4, −2, 2,

Answer:
The range is all the y values.
Therefore, the range is : {-4,-2,2}.....I realize choice c has all the y values listed, however, if u have repeating y values, u only have to list it once.
