The relation that is a function is:
b. y = 2x² - 3x + 7
<h3>When a relation is a function?</h3>
A relation is a function if each value of the input is mapped to only one value of the output.
Hence, when both x and y are squared, we have that 
, hence it is not a function. This is the case for items a and c.
For item d, we have that the relation can be simplified as follows:
x = -y² + 3y
x = y(-y + 3)
The solution above, is associated to two values of y, hence it is also not a function. Then the function is given by:
b. y = 2x² - 3x + 7
In the solution, it can be seen that for each input x, only one value of y can be generated.

Answer:
The stereo is now being sold for $227.80.
Step-by-step explanation:
To calculate percentage discounts, multiply the original price (268) by the discount percentage (.85). Make sure to put move the percentage value two places to the right before multiplying, as percentages are percentages of a whole.
268 * .85 = 227.8
Answer:
110 Degrees
Step-by-step explanation:
Every interior triangle equalls 180 degress. So you subtract what you already have from 180.
30+40+x=180
70+x=180
180-70=110
