Question

For the given equation, find the values of a, b, and c, determine the direction in which the parabola opens, and determine the y-intercept. Decide which table best illustrates these values for the equation:

Answer 1

Answer:

Table C

Step-by-step 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
