(3) let p(x) denote the collection of all finite subsets of a set x what is the cardinality of the set p(r)? prove your claim

if you mean

then it's c. 8, -7/3

but if you mean

then it is

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

answer: the answer to your question is parallel

range is infinite on both x and y axis positive and negative
