Answer:
f(-2) = 0
Explanation:
f(x) = (2x+4)/6 is a "rule" or like, directions. It says take your number, times by 2, add 4 and then divide by 6.
f(-2) just means to put -2 in place of x. Do the "rule" or follow the directions on the number -2.
f(x) = (2x+4)/6
f(-2) = (2•-2 + 4)/6
= (-4+4)/6
= 0/6
= 0
So f(-2) = 0
