Which graph does not represent a function? On a coordinate plane, a curved crosses the y-axis 1 time and the x-axis 2 times.

On a coordinate plane, a straight line with a negative slope crosses the y-axis 1 time and the x-axis 1 time.

On a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times.

On a coordinate plane, a line with an s curve crosses the y-axis 1 time and the x-axis 1 time.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

what chart am i supposed to follow?

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.

answer is b 270°

i got it down for you chief.
