y = x + 4/x
replace x with -x. Do you get back the original equation after simplifying. if you do, the function is even.
replace y with -y AND x with -x. Do you get back the original equation after simplifying. If you do, the function is odd.
A function can be either even or odd but not both. Or it can be neither one.
Let's first replace x with -x
y = -x + 4/-x = -x - 4/x = -(x + 4/x)
we see that this function is not the same because the original function has been multiplied by -1
. Let's replace y with -y and x with -x
-y = -x + 4/-x
-y = -x - 4/x
-y = -(x + 4/x)
y = x + 4/x
This is the original equation so the function is odd.
Answer: they have 68 servings of ice cream left for the party
Step-by-step explanation:
The Smiths purchased 6 containers of ice cream for a party. Each container holds 9 cups of ice cream. This means that the total number of cups of ice cream that they have is
6 × 9 = 54 cups
Before the party, their sons ate 3 cups of ice cream altogether. This means that the number of cups of ice cream that they have left is
54 - 3 = 51 cups
One serving is 3/4 cup of ice cream. This means that the number of serving that they have left is
51/0.75 = 68
Answer:
y is 1/4 when x is -1 if I did interpret your equation right. Please see that I did.
I believe the equation to be 
. If you meant 
, please let me know.
Thanks kindly.
Step-by-step explanation:
If (-1,y) lies on the graph of , then by substitution we have:
.
We just need to simplify to determine y:
Multiply the 2 and -1:
Use reciprocal rule for exponents to get rid of the negative:
just means 
:
.
A division problem is unsolved, so it is an unknown factor until ithe problem is solved.
