Please help me I will give you extra points and the brain thing. Which statement about this mapping is true? image below

A. The mapping does not represent y as a function of x, because there are more x-values than related y-values.

B. The mapping represents y as a function of x, because each y-value is related to exactly one x-value.

C. The mapping does not represent y as a function of x, because 1 x-value is related to 2 y-values.

D. The mapping represents y as a function of x, because each x-value is related to exactly one y-value.

Need plz been trying to do it for a long time and still haven’t succeeded

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
