y=2(x-4)^2-2
\n" ); document.write( "a. sketch the graph
\n" ); document.write( "Vertex at (4,-2)and opening up.
\n" ); document.write( "\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C2%28x-4%29%5E2-2%29\"\r
\n" ); document.write( "\n" ); document.write( "b. Label the intercepts and vertex
\n" ); document.write( "x-intercepts:
\n" ); document.write( "Let y = 0, then 2(x-4)^2 = 2
\n" ); document.write( "(x-4)^2 = 1
\n" ); document.write( "x^2 - 8x + 16 = 1
\n" ); document.write( "x^2 - 8x + 15 = 0
\n" ); document.write( "(x-3)(x-5) = 0
\n" ); document.write( "x = 3 or x = 5
\n" ); document.write( "------------
\n" ); document.write( "y-intercept
\n" ); document.write( "Let x = 0, then y = 2(-4)^2 -2 = 30
\n" ); document.write( "---------------------------------\r
