How many subsets does the set a have? a={-3,-2,-1,0,1,2,3}

128

Step-by-step explanation:

You find the number of subsets of a set by using the formula .

We have 7 elements so that means we have subsets.

-3.396 = -3.4

-0.708 = -0.7

0.304 = 0.3

0.955 = 1

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
