The double number line below shows the approximate number of pounds in a certain number of kilograms: based on the number line, about how many pounds are there in 4. 5 kilograms?.

table 3 represents a direct variation function. : )

m∠a is 90°

m∠b is 40°

vertical asymptote .

horizontal asymptote .

step-by-step explanation:

given function is .

vertical asymptote is given by setting

denominator =0

when degree of numerator and denominator are same then divide first term of numerator by first term of denominator to get horizontal asymptote.

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.
