Please help I am stuck

C) No, because one x-value corresponds to two different y values.

Here we have x = 3 correspond to y = 4 and y = 3 at the same time.

A function is only possible if any x input leads to exactly one y output. Put another way, we can't have x repeating any values if we want a function.

If you plot the points from the table, then you'll see the graph fails the vertical line test and that's a visual way to see we don't have a function.

Step-by-step explanation:

If one x-value has more than one y-value then it is not a function

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
