Graphing Parabolas and Circles with Radical Functions
When graphing parabolas and circles, solve for to obtain radical functions with both positive and negative branches: . For parabolas: gives . For circles: gives . Key formulas include expressions such as y. This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 5: Rational Exponents and Radical Functions.
Key Concepts
When graphing parabolas and circles, solve for $y$ to obtain radical functions with both positive and negative branches: $y = \pm\sqrt{\text{expression}}$. For parabolas: $x^2 = 4py$ gives $y = \pm\frac{\sqrt{4px}}{2}$. For circles: $(x h)^2 + (y k)^2 = r^2$ gives $y = k \pm \sqrt{r^2 (x h)^2}$.
