The function and why it’s a function

Its Table 3

Step-by-step explanation:

In a function  each x value maps only to one y value.

So the first table is not a function because x=3 maps to 4 different values of y.

Similarly in Table 2,  0  maps to 7 and to -10 so its not a function.

Table 3 is a function because each value of x maps to just one value of y.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
