Question

Which equality represents y = 3x² + 2 written in function notation?f(y) = 3x2 + 2O f(x) = 3x² + 2Of(3) = x2 + 2of(2) = 3x2

Answer 1

In function notation, we write f(x) when x is the input or independent variable.

In this case, x is the independent variable and y is teh dependent variable (y =f(x)).

Then, the right way to write this equality in function notation is f(x)=3x²+2
