6. which of the expressions represent
the distance between -8 and 7 on a
number line? select all that apply.
a.1-8 + 71 b. 17 + 81
c. 1-7 + 8 d. 18 – 7||
e. 17 - 81 f. 1-8 – 71

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

nope.   happens to me as well.

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.
