Explain how to write a function rule from the table below. Then write a function rule.
x = 0|2|4|6
y = 2|1|0|-1
Pls I really need help ASAP
When x increases by 2 y decreases by 1.
The initial value for y is 2 and zaim decreases with 1 which is one half of the increase value for x.
So your function is:
Initial value for y, in this case 2 minus decrease in value for y, in this case one half of the increase in argument x.
y = 2 - x / 2
To write a function rule from a table, we need to identify any patterns or relationships between the values of x (input values) and y (output values). In this table, we can see that as the value of x increases by 2 each time, the value of y decreases by 1.
To write the function rule, we can start by defining the relationship between x and y. In this case, we notice that for each increase of 2 in x, y decreases by 1. Therefore, we can write the relationship as:
y = -1 * (x/2) + b
Now, to determine the value of b, we can substitute the value of x and y from any given point in the table. Let's use x = 0 and y = 2:
2 = -1 * (0/2) + b
2 = -1 * 0 + b
2 = b
Therefore, the function rule for this table is:
y = -1 * (x/2) + 2
