Which is the inverse of the function f(x)=4x^2 ?

  for f(x) = 4x², x≥0, the inverse function is f⁻¹(x) = (1/2)√x

Step-by-step explanation:

Solve for y:

  x = f(y) = 4y^2

  (x/4) = y^2

  ±√(x/4) = y = ±(1/2)√x

The domain of the original function must be restricted if it is to have an inverse. (The inverse relation cannot be double-valued if it is to be called an inverse function.) Usually we choose to restrict the values of x to be positive.

  for f(x) = 4x², x≥0, the inverse function is f⁻¹(x) = (1/2)√x

the first one, all those points on the line just make a strait line.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
