Algebra.Com's Answer #475555 by oscargut(2103) You can put this solution on YOUR website! 1. Given: y=x^2-6x+7 \n" ); document.write( "Find: h and k \n" ); document.write( "x^2-6x+7 = (x-3)^2-2 = 1(x-h)^2+k \n" ); document.write( "Then h = 3 and k = -2 \n" ); document.write( "2. Given: 3y=(x-2)^2-6 \n" ); document.write( "Find: a,b, and c \n" ); document.write( "3y=(x-2)^2-6 \n" ); document.write( "3y = x^2 -4x-2 \n" ); document.write( "y = (1/3)x^2-(4/3)x-2/3 \n" ); document.write( "Then a = 1/3, b = -4/3 and c = -2/3 \n" ); document.write( "3. If the simplest quadratic function is f(x)=x^2, what is a,b, and c equal to? \n" ); document.write( "a = 1 , b = 0 and c = 0 \n" ); document.write( "4. Add a constant to make a^2+a+... a perfect square \n" ); document.write( "Constant = 1/4 because a^2+a+1/4 = (a+1/2)^2 \n" ); document.write( "If you have more questions i can see them if you contact me at: mthman@gmail.com \n" ); document.write( "Thanks \n" ); document.write( " |
