Answer:
C
Step-by-step explanation:
To determine a function rule, look at the table. Input the x and y value from one column into the function to see if it is correct.
Function a: y = 10 - 2x
Input values
22 = 10 - 2(6)
22 = 10 - 12
22 ≠ -2 ❌
As we can see, function a gives us a false statement, so a is incorrect.
Function b: y = 2 - 10x
Input values
22 = 2 - 10(6)
22 = 2 - 60
22 ≠ -58 ❌
We once again get a false answer, so b is also not correct.
Function c: y = 10 + 2x
Input values
22 = 10 + 2(6)
22 = 22 ✔
Finally, we get a true statement, so option c is correct.
Function d: y = 2 + 10x
Just to check that option c is correct, we need to prove that d is incorrect.
Input values
22 = 2 + 60
22 ≠ 62 ❌
This is also wrong, so that proves that c is correct.
I'm always happy to help :)
