6 0

A is the answer, because the highest exponent is 2.

<u>quadratic</u>

A's expression foiled would be 2x^2 + x - 6

B's expression foiled would be 3x - 12, where the exponent on x is only 1.

D's expression foiled would be x^3 - x^2 - 12x, where the exponent on x is 3.

Consider that point A is reflected across the y-axis. What is the distance between point A and the point of its reflection?
Arisa [49]

Answer:

C

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ), thus

A(3, 4 ) → A'(- 3, 4 )

Since the point A and it's reflection lie on a horizontal line then

distance between = | 3 + 3 | = | 6 | = 6

The vertex of this parabola is at (-4,-1). When the y-value is 0, the xvalue is 2
yaroslaw [1]
The standard form for this parabola is x = a(y-k)^2 + h because this is a sideways-opening parabola. Our h and k values for the vertex are (-4, -1). And it goes through (2,0). We just need to solve for the a. Filling in accordingly, 2 = a(0+1)^2-4 so 2 = a - 4. a = 6. A above.

correct answer is 6!
