Final answer:
To rewrite the equation y = -3x² + 6x - 1 using function notation, we can use the notation f(x) = -3x² + 6x - 1.
Step-by-step explanation:
To rewrite the equation y = -3x² + 6x - 1 using function notation, we can use the notation f(x) = -3x² + 6x - 1. This notation represents the function where the value of y is determined by the value of x. So, instead of using y to represent the dependent variable, we use f(x).
