How do I graph
a)y=2x^2-8x+10
b)y=3x^2+12x-7 and it's inverse, and state the domain and range of each.
Please Help.
Correct. Note that range is actually Now what is the domain and range of the inverse?
Pick x values (i.e. x=-2,1,0,1,2,3,4) and evaluate the function at these values. Then plot these points and connect them (make sure the curve looks smooth).Also, how would I go abouts graphing this by hand?
Yes, it seems that they have the same vertex.
Yes.Thanks. Would this method be appropriate to use for the second questions as well?
Yes. This time, look where y=-2,-1,0,1,2,3,4. Then connect the points.Also, for the graphing the inverse by hand I would simply switch the x and y values, correct?
Take note that the domain and the range switch for the inverse.
