Question

PLEASE HELP!Can someone explain this to me? How to find the Function rule? Would it just be "f(x)= ??" ?

Answer 1

The expression "function rule" means the expression that turns an input into an output.

If the input is 'x' and the output is 'f(x)', the function rule is the "body" of the function.

For example:

`f(x)=x\cdot2+3`

The function rule would be the "*2 + 3", that is applied in the input x so it becomes the output f(x).
