Question

what is the domain and range of the equation Y=X^3 + 2  and also determine whether Y is a function of X

anonymous · Answer

domain and range are all real numbers, y is a function of x since for every x there is a y value

anonymous · Answer

i'm told to plot a graph and get the domain and range of the equation

anonymous · Answer

$$f(x) = x^3 + 2$$ is in fact a continuously differentiable function on $$\mathbb{R}.$$

anonymous · Answer

my calculator already did the graphing but i dont know which is the domain or range

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
