Question

The equation below describes a parabola. If a is positive, which way does the parabola open?

Answer 1

Answer:up

Step-by-step explanation:

Answer 2

we know that

the equation

$y=ax^{2}$

describe a vertical parabola with vertex at point $(0,0)$

if  $a> 0$ -------> the parabola open Up and the vertex is a minimum

if  $a< 0$ -------> the parabola open Down and the vertex is a maximum

in this problem we have

$a> 0$ ---> because is positive (given problem)

so

The vertex is a minimum

therefore

the answer is the option C
