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

Answer:
(-4,-5)
Step-by-step explanation:
The slope of the line passing through (3,5) and (-2,1) would be:
It would be:
y2 - y1 / 2 and x2 - x1 / 2
= 1 -5 / 2 and -2 -3 /2
= -4/2 and -5/2
= (-4,-5)
Hope this helped :3
Price of an adult ticket: $25
Price of a child's ticket is 25-0.20(25) = $20
Total cost = 2 adult tickets + 4 child tickets
= 2(25)+4(20)
= 50+80 = $130
