Vocabulary for Finding the Intercepts, Asymptotes, Domain, and Range From the Graph of a Rational Function Intercepts:The {eq}x {/eq}-intercept(s) are points at which the graph of the function touches the {eq}x {/eq}-axis. It is possible to have zero, on...
The vertex of a parabola is a point at which the parabola makes its sharpest turn. The vertex of f(x) = ax^2 + bx + c is given by (-b/2a, f(-b/2a)). Learn how to find vertex of a parabola from different forms like standard form, vertex form, and inter

To find the x-intercept, substitute y = 0 then solve. 0 = 10x - 12 12 = 10x x = 12 / 10 = 6/5. (or 1.2) Therefore, the x-intercept is 6/5. Since this equation is in the form y = mx + b, and b is the value of y at the y-intercept, you also know the y-intercep...

While this way won't always work, it is probably the easiest way to do it, so knowing how to is really helpful. Factoring the quadratic will change it from standard form into intercept form, which will tell us exactly where the parabola crosses the x-axis (where its x intercepts are),...
