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 of the function.

I cant undestand how to find the domain and range. Actually I dont understand any of it.

Check out the domain and range examples here:

Have you plotted the points; which type of function do you think it is?

(I think you could get away with exponential or parabolic, unless I'm missing a definitive contradiction to the parabola.)
