There are 10 total digits ( 0, 1 , 2, 3, 4, 5, 6, 7,8 ,9)
1st digit can be 1 of 10
2nd digit can be 1 of 9 ( 10-1 because a number cannot repeat)
3rd digit can be 1 of 8 ( 9-1 because no number can repeat)
total combinations = 10 * 9 * 8 = 720
Answer:
f(x) = 11 - x
Step-by-step explanation:
We have to find a function that has a graph as x + y = 11.
Now, the equation given is
x + y = 11
⇒ y = 11 - x
So, if we consider x as an independent variable and y as a dependent variable whose values are dependent on the values of x, then er can write y = f(x) = 11 - x
So, the function f(x) = 11 - x has the same graph as x + y = 11. (Answer)
