Question

draw the graph of y = x square - X + 9 and find the zeros​

Answer 1

$Given \: y = x^{2} - x + 9$

$\begin {tabular} {|c|c|c|c|c|c|c|c| } </p><p>\cline {1-8} x&-3&-2&-1&0&1&2&3 \\</p><p>\cline {1-8} x^{2}&9&4&1&0&1&4&9 \\</p><p>\cline {1-8} -x&3&2&1&0&-1&-2&-3 \\</p><p>\cline {1-8} 9&9&9&9&9&9&9&9 \\</p><p>\cline {1-8} y&21&15&11&9&9&11&15 \\</p><p>\cline {1-8} (x,y)&(-3,21)&(-2,15)&(-1,11)&(0,9)&(1,9)&(2,11)&(3,15)\\</p><p>\cline {1-8}</p><p>\end {tabular}$

$Plot \: points \: on \:the \:graph \: join \:them \\with \: a \: smooth \:curve \: we \: get \: a \\parabola .$

$It \: doesn't \: intersecting \: x -axis .$

$\therefore It \:has \: no \: real \: zeroes .$
