Use the parabola tool to graph the quadratic function. f(x)=2x^2+4x−16 Brainlest and 35pts plz help me!!!

you would place the y-intercept at (0,-16).  and then the coordinates would be (-4,0) and (2,0). and the graph would be facing up or positive .

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
