Mathematics: Part a: do the data in the table represent a function? justify your answer. part b: compare the data in the table with the relation f(x)=3x-10. which relation has a greater value when x=8 part c: using the relation in part b, what is the value of x if f(x)=80 ?

Sure it's a function. Each input x in its domain gives a single value for y, which is all we need for a function.

f(8)=3(8)-10=24-10=14

That's bigger than the value of the table function at 8, which is 4.

f(x)=80 means

80 = 3x - 10

90 = 3x

x = 30
