give the domain, range, and zeros of: f(x)=absoulte value of x-3. f(x)=x^2-4x-8 f(x)=(x+1)(x+1)(x+1). f(x)=4 f(x)=-'9x-1)^2+16 y=squareroot x. i don't understand how i konw what the range, domain, and zeros are...please give some answers so i get it

i have a question.... when i get a function, how do i konw if it has an inverser... for example, y=ab.solute value x, then -2. i plugged in x=ab.solute val. of y, then -2. but how do i know if that is an inverse??

Math
how do i know what the domain is in these problems... i know that domain is the x value but how can i tell what it is? y=1/x y=3/x^2-49 y{x} y=square root of 3-x y=[x].
