Question 932989
How many x-intercepts does the graph of {{{y = x^2}}} have?


to find x-intercepts, set {{{y=0}}}

{{{0 = x^2}}}=> {{{x = sqrt(0)}}} => {{{x = 0}}}

answer is: {{{0}}} x-intercepts


{{{ graph( 600, 600, -6, 5, -10, 10, x^2) }}}

as you can see, the graph only touches x-axes at {{{0}}}
