Let us consider a quadratic equation in Vertex Form: #color(blue)(y=f(x)=(x-3)^2+8#, where. #color(green)(a=1; h=3; k=8# Hence, #color(blue)("Vertex "= (3, 8)# To find the y-intercept, set #color(red)(x=0# #y=(0-3)^2+8# #y=9+8# #y= 17# Hence, the y-intercept: #color(blue)((0, 17)# We can use a table of values to draw the graph:

Graph the equation. y = − 2 ( x + 5) 2 + 4. This equation is in vertex form. y = a ( x − h) 2 + k. This form reveals the vertex, ( h, k) , which in our case is ( − 5, 4) . It also reveals whether the parabola opens up or down. Since a = − 2 , the parabola opens downward.
