. If x = -4 and y = 2x – 1, then y equals what number?

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

What is the value of x in the following equation. -x ^3/2 = -27

What is the domain of the given function? {(3,-2), (6, 1), (-1, 4), (5,9), (-4, 0); o {x | x= -4,-1, 3, 5, 6} o {yl y = -2,0, 1,4,9} o {x|x = -4,-2, -1,0, 1, 3, 4, 5, 6, 9} o y y = 4,-2, -1, 0, 1, 3, 4, 5, 6, 9}
