A function will not have any repeating x values....it can have repeating y values, but all the x values have to be different for it to be a function.
A is a function because all the x values are a different number
B is not a function because u have repeating x values...u have repeating 4's and repeating 9's
An integer is like a whole number (28 is an integer).
Irrational means the decimal goes on forever.......and cannot be written as a fraction (0.9857... is irrational).
A number that is not real is the squareroot of a negative, or something times i, or dividing by zero (5/0 is unreal).
A rational number can be written as a fraction (like 8 and 1/7).
Answer:
Unit 4- Expressions and Equations: In this unit, students build on their knowledge from unit 2, where they extended the laws of exponents to rational exponents. Students apply this new understanding of number and strengthen their ability to see structure in and create quadratic and exponential expressions.
Answer:

Step-by-step explanation:
So we have the equation:

First, subtract 9 from both sides:

Divide both sides by -4:

Definition of Absolute Value:

Subtract 3 from both sides:

Divide both sides by 5:

And we're done!
