Answer:
The inverse of the function is ±sqrt( (x+4)/2
Step-by-step explanation:
Set the function equal to y
y = 2x^2 -4
Exchange x and y
x = 2y^2 -4
Solve for y
Add 4 to each side
x+4 = 2y^2 -4+4
x+4 = 2y^2
Divide each side by 2
(x+4)/2 = 2/2y^2
(x+4)/2 = y^2
Take the square root of each side
±sqrt( (x+4)/2 )= sqrt(y^2)
±sqrt( (x+4)/2 )= y
The inverse of the function is ±sqrt( (x+4)/2
5/3
Csc is equal to 1/sin
Sin= opposite/hypotenuse
So just take the inverse of what sine would be
Sin= 3/5
So Csc=5/3 :)
Answer:
yes cuz yes plus yes times yes is yes squred
Step-by-step explanation:
The vertex is the center point of the line or the axis of symmetry
So your answer should be (-2, -5)
By comparing equation
a=2,
x-h=x+1, -h=1, h=-1
k=-3
h=-1 move graph to the left (because h=-1 is negative) by 1 unit, h is moving to the left or to the right(horizontal shift)
a=2 vertical streaching
k=-3, k shows vertical shift , k=-3 moving 3 units down because it is negative
