(7-1/8) - (1-7/8) = 57/8 -15/8 = 21/4
The answer is (4x11)-7 i believe
<h3>
Answer: Yes it is a function.</h3>
Reason:
There are no repeated x values, so each x input leads to exactly one y output. That's why we have a function.
If we had something like (1,18) and (1,12), then the input x = 1 leading to simultaneous outputs y = 18 and y = 12 would mean we wouldn't have a function.
-28 because if you add 8 to -120 you get -112 then divide it by 4 and you got -28
