What is the zero of the linear function $$y = -4x + 24$$ ?

The zero is the value of x when y = 0. For $$y = -4x + 24$$ , setting y to 0 gives $$0 = -4x + 24$$ , solving for x gives $$x = 6$$ .

What is the zero of the linear function $$y = 5x + 20$$ ?

The zero is the value of x when y = 0. For $$y = 5x + 20$$ , setting y to 0 gives $$0 = 5x + 20$$ , solving for x gives $$x = -4$$ .

How do you find the zeros of a quadratic function?

To find the zeros of a quadratic function $$f(x) = ax^2 + bx + c$$ , you can use the quadratic formula: $$x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}$$ .

What is the standard form of a quadratic function?

The standard form of a quadratic function is $$f(x) = ax^2 + bx + c$$ , where a, b, and c are constants and $$a \neq 0$$ .

What does the graph of a quadratic function look like?

The graph of a quadratic function is a parabola, which opens upwards if $$a > 0$$ and downwards if $$a

What is the vertex of a parabola?

The vertex of a parabola is the highest or lowest point on the graph, depending on the direction it opens. It can be found using the formula $$x = -\frac{b}{2a}$$ .

What is the significance of the y-intercept in a linear function?

The y-intercept is the point where the graph of the function crosses the y-axis. It is represented by the value of b in the equation $$y = mx + b$$ .

How do you determine the slope of a linear function?

The slope of a linear function is determined by the coefficient of x in the equation $$y = mx + b$$ . It represents the rate of change of y with respect to x.

What is the area of a rectangle?

The area A of a rectangle is calculated by multiplying its length and width: $$A = length \times width$$ .

What is the difference between a linear function and a quadratic function?

A linear function has a constant rate of change and is represented by a straight line, while a quadratic function has a variable rate of change and is represented by a parabola.
