Question 140331
a)


Here's the graph of {{{y=x^2}}}


{{{ graph( 500, 500, -10, 10, -10, 10,x^2   ) }}}




b)


Here's the graph of {{{y=x^2-3}}} (notice it is simply the graph from part a) but has been shifted down three units)


{{{ graph( 500, 500, -10, 10, -10, 10,x^2-3   ) }}}





c)


Here's the graph of {{{y=(x+1)^2}}} (notice it is simply the graph from part a) but has been shifted to the left one unit)


{{{ graph( 500, 500, -10, 10, -10, 10,(x+1)^2) }}}
