1. CPM Section 2.1 Part II Normal Domains

2. Once again, the domain of a relation such as would be _____________________________________, while the range would be ___________________________________. Later in the year we will discuss imaginary numbers but right now we are limited to the set of real numbers (__). Thus, when determining the normal domain of a relation, there are two things that must be avoided. 1. _____________________________________________________________ 2. _____________________________________________________________ the #’s that you put in for x the #’s we get for y Domain (x’s) (input) Range (y’s) (output) We can’t divide by zero (set denom=zero) We can’t take the square root of a neg # ***If there is no variable in the denom or in a radical, the domain is i

5. Homework: Page 68-69 #’s 14-34 When the radical is in the denominator, set the radicand greater than zero cause the denominator can never equal zero
