Answer: Yes it is a function.
This is because any x input leads to exactly one y output.
The graph passes the vertical line test. It is impossible to draw a single vertical line through more than one point on the parabolic curve.

Answer:
Carmen has the biggest red to green apple ratio
Step-by-step explanation:
Red to green apple ratios are, in order, 20:12, (5:3), 12:10 (6:5), and 16:20 (4:5). 5:3 is the biggest red to green apple ratio because for every 5 red apples Carmen has 3 green apples.
Answer:
x = 3
Step-by-step explanation:
6 <em>+</em><em> </em><em>5</em><em>x</em><em> </em>= 21
<em>5</em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>5</em>
<em>x</em><em> </em><em>=</em><em> </em><em>3</em>
I hope this helps

To obtain the graph of the function y = |x+2| we have to make a table of values of x to find the values of y. The absolute value or modulus of a real number is its numerical value without care its sign. For example, the absolute value of |4| and |-4| is 4.
In order to make a graph we are going to use the values (-3, -2, -1, 0, 1, 2, 3) for x.
x = -3
y = |-3 + 2| = |-1| = 1
x = -2
y = |-2 + 2| = |0| = 0
x = -1
y = |-1 + 2| = |1| = 1
x = 0
y = |0 + 2| = |2| = 2
x = 1
y = |1 + 2| = |3| = 3
x = 2
y = |2 + 2| = |4| = 4
x = 3
y = |3 + 2| = |5| = 5
<u> x ║ y</u>
-3 1
-2 0
-1 1
0 2
1 3
2 4
3 5
