What is the range of the function graphed below?
1) 1 2) -3 3) -2 4) -3

B

-3 < y ≤ 3

Step-by-step explanation:

There is a closed circle on 3 and the line is pointing downward so the sign would be less than or equal to.

There is an open circle on 3 and the line is pointing upwards so the sign is greater than.

(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
