Identify the vertex and the y-intercept of the graph
\n" ); document.write( "of the function y = -3(x + 2)^2 + 5
\n" ); document.write( "----------------
\n" ); document.write( "The function is in the vertex form y = a(x-h)^2+k
\n" ); document.write( "where the vertex is (h,k).
\n" ); document.write( "---
\n" ); document.write( "Your problem: vertex is (-2,5)
\n" ); document.write( "When x = zero, y = -3*2*2+5 = -7
\n" ); document.write( "so the y-intercept is (0,-7.
\n" ); document.write( "----
\n" ); document.write( "Since a = -3 is negative the parabola opens downward.
