Answer:
Number 14 is a function and Number 16 is NOT a function.
Step-by-step explanation:
To check if a set of numbers form a function, you can look at the x values or the imput values.
For number 14 the x values are : 4,-3,-4,5,6. When looking at these values, there can only be one of each number.
For example in number 16, there's two 0's and we cannot allow that! So therefore, number 16 is not a function.
Also note, the y values are called the outputs.
A function is only allowed to have ONE imput with each output.
Hope this helps! :)
Answer : B
x^2-9x+14
Lets factor 
We find out two factors whose product is +14 and sum is -9
Two factors are -2 and -7, we split the middle term -9x using -2 and -7
Group first two terms and last two terms
Then factor out GCF from each term
so x-2 is one of the factor
Answer:
45d + 42
Step-by-step explanation:
-7(-7d - 6) - 4d
49d + 42 - 4d
49d - 4d + 42
45d + 42
Answer: The side length of the other sides are the same as the first side.
