Find the inverse of the function y=2x^2

to find the inverse  exchange the x and y and then solve for y

y =2x^2

x =2y^2

divide by 2

x/2 = y^2

take the square root of each side

sqrt(x/2) =y

the inverse of y =2x^2  is sqrt(x/2)

its a straight line parallel to the time axis

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
