Answer 2

Table C

Explanation:

we have

`y=-4x^(2)`

The quadratic equation in standard form is equal to

`ax^(2)+bx+c=0`

so

In this problem

`a=-4, b=0,c=0`

The y-intercept is the value of y when the value of x is equal to zero

`y=-4(0)^(2)=0`

The y-intercept is the point (0,0)

The coefficient a is negative, therefore the parabola open down
