Best ResponseYou've already chosen the best response.1Hint: To find the domain, find all the values of x that make the denominator equal to zero To find the range, find the inverse function and repeat the same steps to find the domain

Best ResponseYou've already chosen the best response.0I'm confused with this one because there are two lines. It throws me off. Should I put them together or what?

Best ResponseYou've already chosen the best response.0This is what I'm having trouble with. I don't know how to find the domain and the range for these kinds of functions

Best ResponseYou've already chosen the best response.1The domain is all the values that you are allowed to input into the equation.

Best ResponseYou've already chosen the best response.1ignore the graph look at the equation y = (1/x)  5 x cannot be 0 because if it were, then you would be dividing by zero (which is not allowed) so you must restrict 0 from the domain any other number is just fine So the domain is the set of all real numbers but x cannot be zero

Best ResponseYou've already chosen the best response.1the range can be found in a similar way, but you first need to find the inverse function

Best ResponseYou've already chosen the best response.0I want to be able to look at the graph and know the domain and the range

Best ResponseYou've already chosen the best response.1I'll show you how to get the inverse function Swap x and y, then solve for y y = (1/x)  5 x = (1/y)  5 x+5 = 1/y y(x+5) = 1 y = 1/(x+5) So the inverse function is y = 1/(x+5)
