The vertex of this parabola is at (-3, 6). Which of the following could be its equation? A. y = -3(x + 3)2 + 6
B. y = -3(x + 3)2 - 6
C. y = -3(x - 3)2 + 6
D. y = -3(x - 3)2 - 6

Answers

Based on the calculations, the equation of this parabola is equal to: A. y = -3(x + 3)² + 6.

How to determine the equation of a parabola?

Mathematically, the standard equation with the vertex for any parabola is given by:

y = a(x - h)² + k.

where:

  • h and k are the vertex.
  • a is a point.

Substituting the given parameters into the formula, we have;

y = -3(-3 - (-3))² + 6

y = -3(x + 3)² + 6

Hello,

A is your answer

(-3,6) must be a point of the curve.

A) if x=-3 then y=-3(-3+3)²+6=6
y'=-3(x+3)=0==>x=-3
and y=6

B) if x=-3 then y=-3(-3+3)²-6=-6 and not 6
 
C) if x=-3 then y=-3(-3-3)²+6=-3*36+6= -102 and not 6

D) -3(-3-3)²-6=-3*36-6=-114

Megan draws a triangle on coordinate axes. She reflects the triangle across the y-axis and then translates it 5 units to the right. Which statement is true about the triangle formed from these transformations?A. It will be larger than the original triangle
B. It will be smaller than the original triangle
C. It will be congruent to the original triangle
D. It will be a different shape then the original triangle

Answers

Answer C: It will be congruent to the original triangle. Reflections and translations do not affect the size of a shape, only it’s position and the way it is viewed.

Final answer:

The triangle formed from reflecting the original triangle across the y-axis and then translating it 5 units to the right will be congruent to the original triangle.

Explanation:

The triangle formed from reflecting the original triangle across the y-axis and then translating it 5 units to the right will be congruent to the original triangle.



When a figure is reflected across the y-axis, its shape remains the same, but its orientation is flipped. Then, by translating the reflected triangle 5 units to the right, we are simply shifting it horizontally without changing its size or shape.



Therefore, the statement that is true about the triangle formed from these transformations is C. It will be congruent to the original triangle.

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!What are the equations for the vertical and horizontal asymptotes of the function?

Answers

Answer: (A) vertical asymptote: x = 2, horizontal asymptote: y = 1

Step-by-step explanation:

f(x) = (1)/(x-2)+1

Vertical Asymptote is the restriction on the x-value.  The denominator cannot be zero, so x - 2 ≠ 0  ⇒  x ≠ 2

The restricted value on x is when x = 2  which is the vertical asymptote

Horizontal Asymptote (H.A.) is the restriction on the y-value.  This is a comparison of the numerator (n) and denominator (m).  There are 3 rules that will help you:

  • n > m    No H.A. (use long division to find slant asymptote)
  • n = m    H.A. is the coefficient of n divided by coefficient of m
  • n < m    H.A. is 0

In the given problem, n < m so y = 0, however there is also a vertical shift of up 1 so the H.A. also shifts up.  This results in H.A. of y = 1
