x - 1 2 3 4 5
y - 9 8 7 6 5
what is the function rule for this given table
y=10-x
Thank You Dr Russ
To find the function rule for the given table, we need to observe the pattern between the values of x and y.
Looking at the x-values, we can see that each number increases by 1 from the previous number. So the pattern is that x is incrementing by 1, starting from 1.
Now, let's look at the y-values. As x increases by 1, y decreases by 1. So the pattern is that y is decrementing by 1.
Based on this pattern, we can determine the function rule:
y = x + (start value of y)
Here, the start value of y is 9, because when x is 1, y is 9. Therefore, the function rule for the given table is:
y = x + 9
