•find the sum of the infinite geometric series 1/2+1/4+1/8+_

43

step-by-step explanation:

the correct answer is x/3+10≥32

hope this !

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
