section9: graph of y^2 = f(x)if you understood the square root graph, this should be absolutely easy for you.
recall the square root graph of y=f(x). the y^2 graph just requires you to draw
BOTH the positive and negative sides of this graph.take this same y=f(x) graph for example:
recall the previous graph that you'd learnt now
reflect the graph about the x-axis and you will get the
negative square root of the y=f(x) graph.
draw both graphs and you will get this:
tada! that's your y^2=f(x) graph. a piece of cake!
now for a random y^2=f(x) graph, which is in green:
ok two topics, 1 question. now that's a big discount! so answer this properly!
this is a graph of y=f(x):
which of the following the the graph of y^2=f(x)?
