Answer:
(-1, -3)
Step-by-step explanation:
The <em>standard form</em> of a quadratic function is
y = ax² + bx + c
The <em>vertex form</em> is
y = a(x - h)² + k
where (h, k) is the vertex of the parabola.
h = -b/(2a) and k = f(h)
In the equation y= -4x² - 8x -7
a = -4; b = -8; c = -7
=====
<em>Calculate h </em>
h = -(-8)/[2(-4)]
h = 8/(-8)
h = -1
=====
<em>Calculate k </em>
k = -4(-1)² -8(-1) -7
k = -4 +8 -7
k = -3
=====
The vertex is at (-1, -3).
The graph is an <em>inverted parabola</em> with its vertex at (-1, -3).
