Question

question find the coordinates of the vertex of the following parabola algebraically. write your answer as an (x,y) point. y = 2x² - 8 answer attempt 1 out of 2 submit answer watch video show examples

Explanation:

Step1: Identify vertex x-coordinate

For parabola $y=ax^2+bx+c$, $x=-\frac{b}{2a}$. Here $a=2$, $b=0$.
$x=-\frac{0}{2\times2}=0$

Step2: Find vertex y-coordinate

Substitute $x=0$ into $y=2x^2-8$.
$y=2(0)^2-8=-8$

Answer:

$(0, -8)$
