Which statements about the graph of the function f(x) = -x - 4x + 2 are true? Select three options.
The domain is {XIX -2).
The range is 's 6)
The function is increasing over the interval (-, -2).
The function is decreasing over the interval (-4,-).
The function has a positive y-intercept.

The option "The function has a positive y-intercept" is true because f(0) = 2, which is the y-intercept.

Step-by-step explanation:

(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

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
