Question

X f(x)

0 3
2 3
3 3
4 3
5 3
6 3

Which function matches the table?
A) ƒ(x) = x + 3
B) ƒ(x) = 3
C) ƒ(x) = x3
D) ƒ(x) = x - 3

Answer 1

f(x)=3

Explanation:

If you graph the points shown in the table the result is a horizontal line. Horizontal lines have equations of the form y = # or f(x) = #. In this case, the y-value is 3. Therefore, the function that matches the table is f(x) = 3.

Answer 2

B) f(x) = 3

It’s because all the y values are 3
