We are given the functions $y= x^{2}$ and $y= -x^{2}$ .

let's consider some pairs in the graph of both functions.

in $y= x^{2}$ we have (-2, 4), (2, 4), (3, 9), (-5, 25)

in $y=- x^{2}$ we have (-2, -4), (2, -4), (3, -9), (-5, -25)

so for the same values of x, we have y's of equal value, but different sign.

This means that the functions are the reflections of each other with respect to the x-axis.

Answer: C <span>reflection over the x-axis</span>

Say you are at a grocery store and find an item without a listed unit price. How would you calculate the unit price for this ite

Aneli [31]

Answer:

Unitary Method

Step-by-step explanation:

If the item is not listed with the unit price we can use different methods to calculate its unit price.

Unit price tells us the cost of each pound, ounce or gram, square foot or meter, etc., of the product.

We can use Unitary Method to calculate the price of each unit. The unitary method is a technique which is used for solving a problem by calculating the value of a single unit, i.e. 1 unit (by dividing) and then finding the necessary value by multiplying the single unit value.

For an instance if a bag of 6 pounds of potato says $7.00, to figure out the price of each pound (that is 1 unit) of potato we can use unitary method:

6 pounds costs $7.00

1 pound costs: $\frac{7}{6}=1.17$ dollars.
