Answer:
<h2>Both functions have a y-intercept of -2.</h2>Step-by-step explanation:
The given equation is
This equation belongs to a linear function, which means its graph is a straight line, that means the second choice is wrong, beacuse the graph is a parabola, not a straight line.
Also, the parabola is a movement that increases and decreases at certain intervals, it has both behaviors, so the third choice is also wrong.
The symmetry of this parabola is about the y-axis, however, a linear function doesn't have the same symmetry, so the last choice is wrong.
Therefore, the first choice is the right answer, both function has the same y-intercept at -2.
Remember, in a linear function, the constant term represents the y-intercept.
