Functions and Domains

When finding the domains of even root functions algebraically , we must

• only need to set the radicand equal to zero

• try as many numbers as we can

• set the radicand less than zero

• set the radicand greater than or equal to zero.

When finding the domains of rational functions algebraically, we must

• set the denominator greater than zero first and solve for x.

• set the denominator equal to zero first and solve for x

• set the denominator not equal to zero and solve for x.

• set the numerator equal to zero and solve for x.

• [ -12, 12 ]

• ( -12, 12 )

• ( -12, 12 ]

• Rational Funcitons

• Even Root Functions

• Logarithmic Functions

• Odd Root Functions
