Answer:

Yes, the given relation is a function.

Step-by-step explanation:

Given the quadratic function, y = (x + 1)², and the domain of {-2, -1, 0, 1, 2, 3}:

By definition, a function is a <em>relation</em> in which no two ordered pairs have the same first component (x-values) and different second components (y-values). Observing the given domain, there are no repeating <em>input</em> values.

Therefore, the correct answer is that the relation is a function.

two pounds of grapes cost $6 . complete the table showing the price of different amounts of grapes at this rate
Degger [83]

Answer:

Table shown below

Step-by-step explanation:

To solve this problem let's use proportions.

If 2 pounds of grapes cost $6, half the amount will cost half the dollars, so the last row will have $3 in the price

For the second row, we know the price is $1, that is, one-sixth of the original given price. It should correspond to one-sixth of the amount of grapes or 2/6 pounds.

Simplifying the fraction, we get 1/3 or 0.33 pounds
