The symbol f(x) represents a function.
f is the function, x is the input.
f(1) = 3
f(2) = 6
You can figure out that the function is times 2
f(x) = 2x
Here is a function problem:
f(x) = ax^2 + bx + c
f(0) = 4
f(1) = 15
f(2) = 36
What is product abc?
Anyone is welcome to answer this problem :)
Notes: Function does not have to be f, it could be any letter
p(x) or b(x) both work!
I hope this helped,
