Clive needs to write 20 paragraphs for a school assignment. He has already written 10 and can write 5 paragraphs per hour. Clive solves for the number of hours it will take to complete his assignment by subtracting 10 from 20 and then dividing by 5.
Which of the equations below can be solved using the same steps?
O A 10z +5 - 20
OB. 5z + 10 - 20
OC. 5z + 10% = 20
OD. 20z - 10% = 5

1. A relation is a set from x to a set y is called a function if each element of c is related to exactly one element in y. That is,given an element c in c, there is only one element in y that x is related to.
2. You can set up the relation as a table of ordered pairs. Then, text to see if each element in the domain is matched with exactly one element in the range . if so you have a function
3. The domain is the set of all possible x-values which will make the function "work" and will output real y- values .When finding the domain , remember :the denominator (bottom) of a fraction cannot be zero .
