Best ResponseYou've already chosen the best response.0domain and range are all real numbers, y is a function of x since for every x there is a y value

Best ResponseYou've already chosen the best response.1graph itdw:1327462207763:dw does it pass the vertical line test for a function.. that is will a vertical line only cut the curve once... look at the graph... what values of x can you put in.... this gives the domain... what values of y do you get as output.... Domain: all real x Range: all real y, the curve is continuous and a function

Best ResponseYou've already chosen the best response.0The graph is just that of x^3 but shifted 2 units up the yaxis, and you can't 'get the domain and range' unless you like drawing forever and ever and ever...

Best ResponseYou've already chosen the best response.0\[f : \mathbb{R} \longrightarrow \mathbb{R}\] i.e. f maps the reals into itself

Best ResponseYou've already chosen the best response.0he has the right graph. Do you know what the graph of x^3 looks like? It has two turning points, comes up from negative infinity in the lower left quadrant, turns to hit zero, and as it enters the upper right quadrant it turns again to go off to positive infinity. Adding any scalar constant will just translate the graph up or down, depending on the sign of the constant.
