i need help... i dont know to explain this or how to solve it.
Find the function rule:
x= -2,-1,0,1,2
y= 9,4,-1,-6,-11
Function Rule:
5x -1= y
ooops. That's actually negative 5 not positive.
thanks so much!
Your welcome :)
To find the function rule, we need to determine the pattern or relationship between the given x-values and their corresponding y-values.
Let's examine the pattern between the x-values and y-values:
For x = -2, y = 9.
For x = -1, y = 4.
For x = 0, y = -1.
For x = 1, y = -6.
For x = 2, y = -11.
To find the function rule, we need to identify the mathematical operations or calculations that transform the x-values into the y-values.
We can observe that the y-values decrease by 5 each time the x-values increase by 1. This suggests that the function rule might involve subtraction and multiplication.
To find the function rule, we can start by subtracting 5 from each y-value:
9 - 5 = 4
4 - 5 = -1
-1 - 5 = -6
-6 - 5 = -11
We can notice that each y-value after subtracting 5 is equal to its corresponding x-value multiplied by -5.
Therefore, the function rule is y = -5x.
In summary, the function rule is y = -5x, which means that for any given x-value, the corresponding y-value can be found by multiplying the x-value by -5.
