Which set of output values correctly complete the function table?
A) 8,2-12
B) 8,0,12
C) 8,0,-12
D) -8, 0 12

The output and the input is the picture example and I need to figure out what the output is. This is for a test on USA Test Prep.
y=2x - 4
so pick any value for x, and calculate the value of y.
For example, if x=6, then
y = 2*6-4 = 12-4 = 8
So that eliminates D.
Now go on to see the other two values for y.
Hi
To complete the function table for the given function y=2x - 4, we need to substitute the given input values of x into the function and calculate the corresponding output values of y.
Let's evaluate the function for each input value:
For x = 6:
y = 2(6) - 4
y = 12 - 4
y = 8
For x = 2:
y = 2(2) - 4
y = 4 - 4
y = 0
For x = -4:
y = 2(-4) - 4
y = -8 - 4
y = -12
So, the correct set of output values that completes the function table is:
Input (x): 6, 2, -4
Output (y): 8, 0, -12
Therefore, the answer is C) 8, 0, -12.
To find the output values for the given function table, you need to substitute the given input values into the function and calculate the corresponding output values.
Let's use the function y = 2x - 4 and substitute each input value one by one:
For x = 6:
y = 2(6) - 4 = 12 - 4 = 8
For x = 2:
y = 2(2) - 4 = 4 - 4 = 0
For x = -4:
y = 2(-4) - 4 = -8 - 4 = -12
Now, let's compare these calculations with the options provided:
A) 8, 2, -12 - This matches the calculated output values, so A) is correct.
B) 8, 0, 12 - The second output value 0 is incorrect, so B) is not correct.
C) 8, 0, -12 - This matches the calculated output values, so C) is correct.
D) -8, 0, 12 - The first output value -8 is incorrect, so D) is not correct.
Therefore, the set of output values that correctly completes the function table is either A) 8, 2, -12 or C) 8, 0, -12.
