Function Notation Practice - 1

Front

Given: f(x) = 3x² + 3, find f(0).

Back

f(0) = 3.

Front

Given f(x) = x² - 3x, find f(-3).

Back

f(-3) = 18.

Front

Given: f(x) = -3x + 3, find f(0).

Back

f(0) = 3.

Front

If f(x) = 3(6 - x), find f(-8).

Back

f(-8) = 42.

Front

If f(x) = -3x - 8, find f(-1).

Back

f(-1) = -5.

Front

What is function notation?

Back

Function notation is a way to represent a function using symbols, typically f(x), where 'f' is the function name and 'x' is the input variable.

Front

What does f(0) represent in a function?

Back

f(0) represents the value of the function when the input is 0.

Front

How do you evaluate a function at a given point?

Back

To evaluate a function at a given point, substitute the value of the input variable into the function's equation.

Front

What is the general form of a quadratic function?

Back

The general form of a quadratic function is f(x) = ax² + bx + c, where a, b, and c are constants.

Front

What is the significance of the coefficient 'a' in a quadratic function?

Back

The coefficient 'a' determines the direction of the parabola: if 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.
