A relation is a function if you associate exactly one output for every input. This means that, when you choose a value for x, there must be only one correspondent value for y. This only happens in the top-right parabola.
2x - 6 = 2 • (x - 3)
2 = 0
x-3 = 0
x=3
Answer:
-6
Step-by-step explanation:

-3 × -3 = 9
7 × -3 =-21
9 - 21 +6 = -6
Let's solve for the answer to determine if it is rational.

it is a rational number.
