The graph shows a
piecewise function, meaning that different functions are shows at different intervals (ranges of x-values).
1) One of the graphs is part of a parabola, meaning the equation is quadratic (has
). That equation must be
.
2) The other graph is a straight line, meaning it must be a linear equation. That equation must be x + 4.
Looking at the entire graph, you can see that the parabola starts from the left and ends with an open circle at x=2. An open circle means that the graph doesn't have a value at that point, x=2. The linear line starts with a filled point at x=2 and continues to the right. That means we're looking for the choice where:
1)
Since x=2 cannot be a point in the graph, and less than 2 means that the graph includes everything to the left of 2, but not including 2
2)
Since x=2 is a point in the graph, and greater than or equal to 2 means that the graph includes 2 and everything to the right of it

Answer: -4x - y = -50 (second option)
Step-by-step explanation: The only way lines won't intersect is if they're parallel. Parallel lines have the same slope --> the line must have a slope of -4x.
Option 1:
- y = 4x - 200 (add 4x to both sides)
- <em>Different slope.</em>
Option 2:
- -y = 4x - 50 (add 4x to both sides)
- y = -4x + 50 (divide by -1)
- <em>Same slope.</em>
Option 3:
- -y = -4x - 200 (subtract 4x from both sides)
- y = 4x + 200 (divide by -1)
- <em>Different slope.</em>
Option 4:
- -y = -4x - 50 (subtract 4x from both sides)
- y = 4x + 50 (divide by -1)
- <em>Different slope.</em>
