What would be the set builder and interval notation for this?
Q. 36 -2x + 20 I need to know how to write the set builder and the interval notation. Can someone show me how to determine that and how to write it using the symbols? Thanks

A. x>= -8 start by subtracting 20 from both sides. 36-20=16 -2x+20-20=-2x Then divide 16 by -2 to get the x alone 16/-2=-8 set builder notation : {x/x>=-8} Interval : [-8]

How can I state this domain in set-builder notation?
Q. f(x) = 2x^1/3 Please be very detailed. I will select a best answer. I know the answer is "The domain of f(x) = 2x^1/3 is {x|x is a real number}. I don't understand what it means by {x|x is a real number}

A. {x | x is a real number} is the set of all x such that x is a real number. This means that for every real number x, the function is defined. If the function was f(x) = 1/x then the domain is {x | x does not equal zero} since the function is defined everywhere except at x = 0. The vertical line in {x | x is a real number} is the phrase "such that".
