Answer:
The function f has an inverse because it is one-to-one.
Step-by-step explanation:
The condition for a function to have an inverse is that every x coordinate maps to a single y - coordinate. As illustrated by the diagram attached in the second picture, every x value maps to one y value therefore satisfying the condition making the function have an inverse.
You need to know:
Be careful though:
Using this principle, we can say:
12 1/3 = 37/3
3 2/3 = 11/3
Quantity of juice left = Initial quantity - Quantity drunk
So:
Quantity of juice left = 37/3 - 11/3 = 26/3
There will be 26/3 ounces of juice remaining after 3 2/3 are drunk from the total of 12 1/3 ounces that Deacon had initially.
It is just y=-4 since the line is horizontal
A. f(x) = |4 - 2x/3|. You could write abs(4 - 2x/3)
b. f(x) = 2x/3 if x < 6
f(x) = 8 - 2x/3 if 6 <= x <= 9
It would be a negative six ,-6, because if you draw a number line and on one side there are positive numbers on the right and on the left there are negative numbers, you would have to go up to ten on both sides one being positive and the other being negative.You will then go on the negative side and move four spaces to the right from the -10 and you will get a -6.
