Which of the following equations describes the function in the table using function notation?

(1 point)

f (x) = 2x - 4
f (x) =1/2x + 4
f (x) = 1/2x - 4
f (x) = 2x + 4

Answer 1

I can’t clearly reconstruct the mapping from the numbers you pasted. Could you re-upload the image or describe the arrows (which input maps to which output)? Then I’ll tell you whether it’s a function and give the exact domain and range.

Meanwhile, I can answer the table question: the rule is f(x) = 2x − 4 (check: f(0)=−4, f(1)=−2, f(2)=0, f(3)=2).
