Question 486102: Hi! can you help me understand the meaning of algebra 2 functions?
Answer by richard1234(7193)   (Show Source):
You can put this solution on YOUR website! Functions are just operations that map some number or set of numbers to another number or set of numbers. They are usually denoted f(x) = ... (or some other letter besides f), so if you define a function f(x) = 2x + 1, then you can evaluate f(x) for a given x value, for example f(4) = 2(4) + 1 = 9. Or, if g(x) = 5x^2 + x, then g(1) = 5(1)^2 + 1 = 6.
