Find the x-intercepts(if they exits) of the following quadratic functions. Graph the function and mark the intercepts.
\n" ); document.write( "f(x) = x^2 - 6
\n" ); document.write( ":
\n" ); document.write( "Understand that in the graphing world y = f(x), so we have:
\n" ); document.write( "y = x^2 - 6
\n" ); document.write( ":
\n" ); document.write( "Understand that the x intercept occurs when y = 0, substitute 0 for y:
\n" ); document.write( "Solve:
\n" ); document.write( "x^2 - 6 = 0
\n" ); document.write( "x^2 = +6; added 6 to both sides
\n" ); document.write( "x = +\"sqrt%286%29\"
\n" ); document.write( "and
\n" ); document.write( "x = -\"sqrt%286%29\"
\n" ); document.write( ":
\n" ); document.write( "These are x intercepts, approx +2.4494897 and -2.4494897
\n" ); document.write( ":
\n" ); document.write( "A graph of this would look like this
\n" ); document.write( ":
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-6%2C+6%2C+x%5E2-6%29+\"
\n" ); document.write( ":
\n" ); document.write( "You can see the x intercepts corresponds to the values we found
\n" ); document.write( ":
\n" ); document.write( "Did this make sense to you now?
\n" ); document.write( "
