Answer:
x cannot be -4,-3, or 13
x can be anything else
Step-by-step explanation:
There are infinitely many values x can take where the relation above will be a function.
For it to be a function, you just need to make sure each x is only assigned one y value.
So x couldn't be -4 because it would by assigned to y=2 and y=0.
x couldn't be -3 because it would be assigned to y=1 and y=0.
x couldn't be 13 because it would be assigned to y=5 and y=0.
So as long as x is not chosen to be -4,-3, or 13 your relation here is a function.

Answer:
f(x)=4−(x−7)
3
Let y=f(x)
So, x=f
−1
(y) ---- ( 1 )
y=f(x)
⇒ y=4−(x−7)
3
⇒ (x−7)
3
=4−y
⇒ x−7=
3
4−y
⇒ x=7+
3
4−y
⇒ f
−1
(y)=7+
3
4−y
.................. [ From ( 1 ) ]
∴ f
−1
(x)=7+
3
4−x
Answer:
<u>The correct answer is A. The cost of pizza in dollars per square inch</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Cost of the pizza = $ 0.10 * π * r², where r = radius of the pizza in inches
2. What does the constant 0.10 in the function represent?
Let's recall the formula of the area of a circle, in this case, the area of the pizza:
Area = π * r², therefore the constant 0.10 that is multiplying the area of the pizza, is the cost of the pizza in dollars per square inch and the total cost is the result of the multiplication of the area by 0.10.
<u>The correct answer is A. The cost of pizza in dollars per square inch</u>
