5.Which of the following functions match these outcomes:
f(1) = 6
f(2) = 8
f(3) = 10
f(4) = 12

f(x) = 5x + 1
f(x) = 4x + 2
f(x) = x2 + 4
f(x) = 2x + 4
f(x) = 12 - 2x

anonymous · Answer

the value inside the parenthesis are the values that you have to plug in the given equations :)

anonymous · Answer

for example f(1)  = 5x +1  = 5(1)+1  = 6

anonymous · Answer

When I did it it fit in to all of them but it said i was wrong.

anonymous · Answer

maybe you should check it carefully and plug in all the values of your of x one by one so that you know the possible outcomes of the given equaions :)

anonymous · Answer

for example in equation 1 you can only plug in x= 1 because if you put other values of x then the outcome would not match the other values.

Thanks I got it!
