x  -2 -1 0 1 2
y .25 .5 1 2 4 
Given the table above, graph the function, 
identify the graph of the function (line, 
parabola, hyperbola, or exponential), 
explain your choice, and give the domain 
and range as shown in the graph, and also 
the domain and range of the entire function.

Plot those points, connect them with a smooth
curve and get this:



That graph looks like an exponential function, 
because an exponential function has the x-axis 
as its horizontal asymptote on the left and it 
passes through y-intercept (0,1) and "sky-rockets"
thereafter on the right.

Its domain is (-¥,¥) because the curve projects 
downward onto the entire x-axis.

Its range is (0,¥) because the entire curve 
projects right and left onto only the top half 
of the y-axis, (0,¥)

BTW its equation is y = 2x.  If you need to know
this and why, post again.
