Algebra 3Chapter 7: Powers, Roots, and RadicalsLesson 5: Graphing Square Roots and Cubed Roots

VOCAB

Radical Function – an equation that contains a square root symbol.

Domain – all x values on the graph

Range – all y values on the graph

Today

Today we will learn how to graph radical equations

Directions (Graphing)

Convert the problem to exponential form

Type it in the calculator

Graph it

KnowledgeStarting Point

a – stretch/shrink (widens) a – negative flips the graph h – moves right or left (opposite)

k - moves the graph up or down

Knowledge

All even powered radicals make c or backwards c

All odd powered radicals make s or z

LETS MAKE THIS CLEAR

FOR TODAY and TODAY ONLYWe will only be looking at half of the

graph of the even radicals This way you can clearly see the

transformation

In the future you need to remember that even powers get plus minus
