The objective of a microscope has a focal length
of 0.80 cm and the eyepiece has a focal length
of 4.0 cm. An object is placed 1.50 cm from the
objective. The final image is formed at the near
point of the eye (25 cm).
a) Calculate the distance of the image from the objective.
b) Calculate the distance from the eyepiece lens of the image in part a.
c) Calculate the angular magnification of the microscope.

it may be wrong but i think its a

i'm on my way to history not a mistory.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
