Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar(s). the vertex of a parabola is (-2, -20), and its y-intercept is (0, -12). the equation of the parabola is y =__x^2 +
__ x +

Step-by-step explanation:

Since the equation of parabola along x-axis is,

Where (h,k) is the vertex of the parabola and a is any point.

Here, The vertex of a parabola is (-2, -20),

Therefore the equation of parabola is,

Since, y-intercept is (0, -12),

Therefore, (0,-12) will satisfy the equation of the parabola,

By putting x=0 and y=-12 in the equation of parabola,

⇒ ( by adding 12 on both sides )

⇒ 8 = 4 a

⇒ a = 2 ( dividing by 4 on both sides )

Thus, the complete equation of parabola is,

⇒

⇒

⇒

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
