When it say find the x intercepts do I graph it or give the variable for the intercept \n" ); document.write( "y=x^2-9x+20 \n" ); document.write( "Usually, if they don't give you the graph or ask for the graph, they want the coordinate of the x intercepts. We find x-intercepts by letting y=0 and solveing for x. \n" ); document.write( "0=x^2-9x+20 factor \n" ); document.write( "o=(x__)(x__) \n" ); document.write( "fille the blanks with two numbers that multiply to give you +20, but add to give you -9. -4*-5=+20 and -4+(-5)=-9 \n" ); document.write( "0=(x-4)(x-5) Let each parentheses=0 and solve for x. \n" ); document.write( "x-4=0 and x-5=0 \n" ); document.write( "x-4+4=0+4 and x-5+5=0+5 \n" ); document.write( "x=4 and x=5 \n" ); document.write( "The x-intercept are (4,0) and (5,0) \n" ); document.write( "Happy Calculating and Happy Thanksgiving!!!\r \n" ); document.write( "\n" ); document.write( " \r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
