C^2 - d^2 / d^2 + cd - 2c^2
= cd + c^2 - 2c^2 - d^2 / d^2
= cd - c^2 - 1 (answer)
Answer:
C
Step-by-step explanation:
In a function, each domain has one range. But a range can have many domains.
Think about it like this:
Patty is eating dinner
Patty is swimming
<em>Both can't happen at the same time. </em>
<em>But:</em>
Patty is eating dinner
Leo is eating dinner
C has two domains of -3, each having different ranges.
Hope that helps, tell me if you need further info. =)
Discrete- there are only a set of values and they do not continue up
There's two possible ways to find the answer to this. First you can find a common denominator to reduce both to. In this case, they can both reduce to a common denominator of 8. So 6/16 reduces to 3/8 and 30/80 also reduces to 3/8, so they are equal. The other way is to use a calculator and turn them into decimals by dividing the numerator by the denominator. They both come out to be .375. Once again they are equal. You can use whichever method is easier for you.
