Question 150918: Where will the vertex of f(x)= -3(x+4)2 + 5 be located?: Where will the vertex of f(x)= -3(x+4)2 + 5 be located?

Notice how f(x)= -3(x+4)^2 + 5 is in vertex form f(x)= a(x-h)2 + k where a=-3, h=-4, and k=5. So the vertex is (h,k) which is (-4,5)


Here's a graph to visually verify the answer:

drawing(500, 500, -10, 10, -10, 10,<BR> grid(1),<BR> graph( 500, 500, -10, 10, -10, 10, -3(x+4)^2 + 5),<BR> circle(-4,5,0.05),<BR> circle(-4,5,0.08),<BR> circle(-4,5,0.10) <BR> ) Graph of f(x)= -3(x+4)^2 + 5 with a vertex of (-4,5)
