The sun is 1.50x10^11 m from earth. How long does it take the suns light to reach earth? How long does it take light to cross the diameter of the earths orbit? Compare this time with the time measured
by Roemer in the 17th century.

what do the notation's look like?

its a 5.5 n

glad that

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 .
