Describe the end behavior of the graph

f(x) > +∞ as x> -∞  and  f(x) > -∞ as x> +∞

Step-by-step explanation:

we know that

The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis.

so

the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ )

In this problem

f(x) > +∞ as x> -∞  (as the value of x decreases the value of f(x) increases)

and  f(x) > -∞ as x> +∞ (as the value of x increases the value of f(x) decreases)

(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
