Graphing quadratic functions

Question

the graph f(x)^2 is transformed to create the graph of h(x)=2f(x) Which graph best represents F and H

Answer 1

h(x) should be the same shape as f(x), with the difference being it will show faster growth than f(x), since it is the same function, just multiplied by 2 at the end. In order to check if you have found the right graph, compare 3 or 4 individual points on the two graphs. Where x = 3 on each, is the y coordinate of h(x) double the y coordinate of the graph of f(x)? If not, this is not the correct graph for h(x). This same test can be done with any value, and will ultimately help you find the correct graph.
