Step-by-step explanation:
x = –2
x = 2
x = 3
Answer:
x = 2
Step-by-step explanation:
The vertex form of the parabola is given by
Comparing this equation with vertex form of a parabola , where (h,k) is the vertex
h = 2
k = 3
Hence, vertex is (2,3)
Now, axis of symmetry of a parabola passes through the vertex and divide the parabola in two equal halves.
Hence, axis of symmetry of the parabola is given by
x = h
x = 2
Third option is correct.
Answer:
The coordinates of D' are (1,-1)
Step-by-step explanation:
The point D in the figure has co-ordinates (2,-2) as shown in the figure.
The figure is dilated by a factor of 1/2
So, multiply the coordinates of D (2,-2) by 1/2
D' = (1/2*2, 1/2*-2)
D' = (1,-1)
So, the coordinates of D' are (1,-1)

C). {-1/4,3}
D). {3/4,-1}
3). What would the graph of g(x)=-(x+2)^2+5 look like?
Answer:
x = ±6i sqrt(2)
Step-by-step explanation:
6x^2 + 432 = 0
Subtract 432 from each side
6x^2 =- 432
Divide by 6
6x^2 /6 =- 432/6
x^2 =-72
Take the square root of each side
sqrt(x^2) = ±sqrt( -72)
x = ±sqrt(-1) sqrt(2*36)
We know the square root of -1 = i
x = ±i sqrt(2*36)
x = ±i sqrt(36) sqrt(2)
x = ±6i sqrt(2)
