Answer:
- (0, 0)
- (1, –1)
- (8, –2)
Step-by-step explanation:
We normally think of the ordered pairs as ...
(x, y) = (x, -∛x)
Another way to think about them is ...
(x, y) = (-y³, y)
I find it a little easier to think about the cube of a number, rather than its cube root.
For the y-values given, -2, -1, 0, 2, the points that will be on the graph are ...
(8, -2), (1, -1), (0, 0), (-8, 2)
The first three of these points are listed in your answer choices.
Answer:
Step-by-step explanation:
{2 + 2w = l
{94 = 2w + 2l
94 = 2w + 2[2 + 2w]
94 = 2w + 4 + 4w
94 = 4 + 6w
- 4 - 4
