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

The leading coefficient (the coefficient of $$x^2$$ ) determines the direction of the parabola: if it is positive, the parabola opens upwards; if negative, it opens downwards.

What is end behavior in the context of polynomial functions?

End behavior describes how the values of a function behave as the input approaches positive or negative infinity, indicating the direction of the graph's tails.

What is a linear function?

A linear function is a function that can be graphically represented as a straight line, typically expressed in the form $$f(x) = mx + b$$ , where m is the slope and b is the y-intercept.

What is the slope-intercept form of a linear equation?

The slope-intercept form of a linear equation is $$y = mx + b$$ , where m represents the slope and b represents the y-intercept.

How do you find the x-intercepts of a quadratic function?

To find the x-intercepts of a quadratic function, set $$y = 0$$ and solve the equation $$ax^2 + bx + c = 0$$ using factoring, completing the square, or the quadratic formula.

What is the quadratic formula?

The quadratic formula is used to find the solutions (roots) of a quadratic equation and is given by $$x = \frac{-b \text{±} \text{√}(b^2 - 4ac)}{2a}$$ .

What does it mean for a function to be increasing?

A function is increasing over an interval if, for any two points $$x_1$$ and $$x_2$$ in that interval, where $$x_1

What is the difference between a function and a relation?

A function is a specific type of relation where each input (x-value) is associated with exactly one output (y-value), while a relation can have multiple outputs for a single input.
