A.for it to be a function, for every input there is 1 coresponding output

so example
(1,2) and (1,3) is not a function
but (1,2) and (4,2) is

alrighty

none of the x values or inputs repeats with a different y so that's good, it's a function


B. according to the table, when x=6, y=14

for f(x)=7x-15
when x=6, then f(6)=7(6)-15=42-15=27

27>14
so f(x) has a greater value when x=6


C. f(x)=7x-15=6
7x-15=6
add 15 to both sides
7x=21
divide both sides by 7
x=3
x is 3 when f(x)=6

How do the graphs of y =1/x and y = 3/x – 4 compare?
Pie
The graphs of y =1/x and y = 3/x – 4 can be compared by saying that c<span>ompared to the graph of y =1/x , the graph of y =3/x – 4 is a vertical stretch by a factor of 3 and a translation of 4 units down. This can be seen clearly when you graph the functions on a x-y coordinate plane.</span>
