Answer:

Step-by-step explanation:

It's a vertical line. Regardless of what point you go to on the line, it always has a value of -3 because it is going vertically (up and down) at -3.

Therefore the equation of a line is x = -3

To answer your question the correct answer would be the last one because you would have to slide the triangle to the right to (1,1) and reflect it over the x-axis so that it became (-1,-1)

hope this helps

Which of the following functions is graphed below.

Valentin [98]

Answer: Option A

$y=\left \{ {{x^2 +2;\ \ x$

Step-by-step explanation:

In the graph we have a piecewise function composed of a parabola and a line.

The parabola has the vertex in the point (0, 2) and cuts the y-axis in y = 2.

The equation of this parabola is $y = x ^ 2 +2$

Then we have an equation line $y = -x + 2
$

Note that the interval in which the parabola is defined is from -∞ to x = 1. Note that the parabola does not include the point x = 1 because it is marked with an empty circle " о ."

(this is $x< 1$ )

Then the equation of the line goes from x = 1 to ∞ . In this case, the line includes x = 1 because the point at the end of the line is represented by a full circle .

(this is $x\geq 1$ )
