Step 1: Find the parent graph (in this case it is y=x^2)
\n" ); document.write( "Step 2: If it has a number after the x^2 the the graph moves up and down
\n" ); document.write( "--------Ex. y=x^2+3 (the red line is the original and the green is the new)
\n" ); document.write( "\"graph%28300%2C200%2C-6%2C6%2C-6%2C6%2Cx%5E2%2Cx%5E2%2B3%29\"
\n" ); document.write( "Step 3: If the equation has a number infront of the x^2 then it changes the slope by that number. (called a vertical stretch)
\n" ); document.write( "--------Ex. y=3x^2
\n" ); document.write( "\"graph%28300%2C200%2C-6%2C6%2C-6%2C6%2Cx%5E2%2C3x%5E2%29\"
\n" ); document.write( "Step 4: if it has a number in parenthesis with the x and whole thing is squared the it moves the graph left or right. If it's a negative number it moves it right. If it's a positive number it moves the graph left.
\n" ); document.write( "-------Ex. y=(x+3)^2
\n" ); document.write( "\"graph%28300%2C200%2C-6%2C6%2C-6%2C6%2Cx%5E2%2C%28x%2B3%29%5E2%29\"
\n" ); document.write( "Step 5: If it has a negative infront of it, then the graph flips upside down.
\n" ); document.write( "-------Ex.-x^2
\n" ); document.write( "\"graph%28300%2C200%2C-6%2C6%2C-6%2C6%2Cx%5E2%2C-x%5E2%29\"
\n" ); document.write( ".
\n" ); document.write( "Now heres and example with all of the steps:
\n" ); document.write( ".
\n" ); document.write( "y = -3(x-2)^2 + 1
\n" ); document.write( "the negative flips the graph
\n" ); document.write( "the 3 make a veritcal stretch by factor of 3
\n" ); document.write( "the 2 in the parenthesis moves the graph right 2
\n" ); document.write( "the one at the end moves the graph up one
\n" ); document.write( "\"graph%28300%2C200%2C-8%2C8%2C-8%2C8%2Cx%5E2%2C-3%28x-2%29%5E2%2B1%29\"
\n" ); document.write( ".
\n" ); document.write( "If any of this confused you just let me know and ill try to explain it better.
