9. Iplay

Much better explanation ty :D

11. Iplay

Would i be using the same method to solve f(x) = 2x +2, find (5)?

12. Akshay_Budhkar

you have to find f(5) ?

13. Iplay

Yes sorry find f(5)

14. Akshay_Budhkar

ok for that u need to just substitute x=5 in the function like in this case f(5)= 2(5)+2=10+2=12

15. Iplay

O easy enough and is this the same for all problems like this?

A function is a set of ordered pairs in which no two ordered pairs have the same first number.
