Since addition is commutative, she can add anyway she wants.
(17+51)+(10+13)
(51+10)+(17+13)
Hope this helps.
Answer:
january really
Step-by-step explanation:
Since this is a fairly small equation, it's pretty easy to plug in a few points to get ordered pairs and sketch a graph:
when x = 0...
f(0) = 2(0)^2
f(0) = 0
(0, 0)
when x = 1...
f(1) = 2(1)^2
f(1) = 2
(1, 2)
when x = -1...
f(-1) = 2(-1)^2
f(-1) = 2
(-1, 2)
from there, you can get a rough sketch of the graph just by plotting those points. essentially, it just looks "skinnier" than your typical parabola because the 2 out front makes the curve steeper.
