The expression is not defined at x= -2 & for all values of x less than -2 .
<u>Step-by-step explanation:</u>
We have , a given expression as : Basically we need to find domain for this function and see for which values of x the above function is undefined . Domain of a function is the set of values of x for which the function is defined . We have a rational expression,
it's a fractional function which means denominator can be 0 . Denominator =
⇒
⇒
⇒
So , . Also , Denominator is a square root expression so it can't be negative inside root ∴
⇒
i.e. x must be greater than -2.
Therefore, the expression is not defined at x= -2 & for all values of x less than -2 .
Answer:
The price per ounce is $0.175.
Step-by-step explanation:
Given:
Number of ounces = 10
Price of 10 ounces = $1.75
We know that, from unitary method, price of a unit quantity is given as:
Here, the number of quantities correspond to the number of ounces.
Total price corresponds to the price of the 10 ounces which is $1.75.
Now, unit rate or price per ounce is given as:
Price per ounce =
Price per ounce = $0.175
Therefore, the price per ounce is $0.175.
