Answer:
Number 1 is a function. If you can draw a vertical line through the line graphed and it doesn't pass through it twice, it is considered a function.
Number 2 is B.
Number 3 is A. **I don't know this one for certain, but I graphed A and B for you.
I don't know number 4.
Number 5 is Beatz on Demand. This company charges $5.99 a month, while iTunez charges $8.99 a month.
Step-by-step explanation:
Below is the graph for number 3.
Answer:
10 pieces
Step-by-step explanation:
Giveb that:
Length of rope = 5 meters
Length per piece of rope cut = 1/2
Number of rope pieces that could be cut out :
Lenght of rope / length per piece cut
5 meters ÷ 1/2 meters
5 * 2 /1
= 10 pieces
The last one. because you are starting 1sec after the can has begun to pour. So, (1, 9.60) and the subsequent ordered pairs are correct

Answer:
f(x)⁻¹ = (x - 11)²
Step-by-step explanation:
To find the inverse of the function, you need to (1) swap the places of the "x" and "y" variables and then (2) solve for "y". Remember, f(x) is another way of writing "y".
y = √x + 11 <----- Original equation
x = √y + 11 <----- Swap variables
x - 11 = √y <----- Subtract 11 from both sides
(x - 11)² = (√y)² <----- Square both sides
(x - 11)² = y <----- Simplify
Another way of writing the output of an inverse function is with f(x)⁻¹.
