Evaluate when w = -1, x = -2, y = -3, z = -4 z/x + -8y + 2w - wxyz

-7

Step-by-step explanation:

w = -1, x = -2, y = -3, z = -4

z/x + -8y + 2w - wxyz

(-4)/(-2) + (-8)(-2)  + (2)(-1) - (-1)(-2)(-3)(-4)

2+ 16 + (-1) - (24)

-7

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
