How do you find the x-intercept of a linear equation?

To find the x-intercept, set $$y = 0$$ and solve for $$x$$ .

What is a quadratic function?

A quadratic function is a polynomial function of degree 2, typically in the form $$f(x) = ax^2 + bx + c$$ .

What is the significance of the discriminant in a quadratic equation?

The discriminant, given by $$b^2 - 4ac$$ , determines the nature of the roots: if positive, two real roots; if zero, one real root; if negative, no real roots.

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

The slope-intercept form is $$y = mx + b$$ , where $$m$$ is the slope and $$b$$ is the y-intercept.

What is the relationship between the roots and coefficients of a quadratic equation?

The sum of the roots is equal to $$-\frac{b}{a}$$ and the product of the roots is equal to $$\frac{c}{a}$$ .

What is the process of factoring a quadratic expression?
