What is the vertex of g(x)=8x^2-64x
2 answers:
<span>The (x,y) point of the vertex is usually labelled as:
Vertex = (h, k)
h = -b / 2a
h = --64 / 2*8
h = 64 / 16
</span><span>h = 4
</span>
<span>To get “k”, input the “h” value into the equation.
<span>k = 8*(4^2) -64*4
</span> <span>k = 8*(4^2) -64*4
</span><span>k = 128 -256
</span><span>k = -128
</span></span><span>Vertex = (4, -128)
</span>
Answer:
Vertex = (4, -128)
