Domain is the x and the range is the y, that being said, 1) domain: 1,3,5 range: 2,4,6 2) you need to solve for x then plug x in and solve for y when solving for x you can plug in a number like 1 3) same circumstance as number 2! Hope this helped!
a) The domain are the x values of the system. So here the x coordinates are: 1, 3, and 5.
b) This equation is a linear equation because x is raised to only one power and it has nothing in the denominator. The domain of any linear equation is all real numbers.
c) For a square root, first set the expression to greater than or equal to 0. [tex] \sqrt{x} +4 \geq 0[/tex] The solve for x. [tex] \sqrt{x} \geq -4[/tex] [tex]x \geq 16

a) 1, 3, and 5 b) all real numbers c) [tex]x \geq 16 [/tex]
