You can put this solution on YOUR website!
x^2 is NEVER negative. Squaring a positive number leads to a positive number. Squaring a negative number gives you a positive result (eg: x = -3 ---> x^2 = (-3)^2 = 9)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So that means (x-2)^2 is NEVER negative based on the same reasoning as above.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiplying some number that's either 0 or positive by 7, which is positive, means the expression 7(x-2)^2 results in a number that's 0 or some positive number.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7(x-2)^2 is NEVER negative.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, c) -3 is NOT a possible output of the function. It's impossible to generate a negative number.
