(part 1 of 2) A glacier advances at 3.7 ×10^-6
cm/s.
How far will it move in 89000 s?
Answer in units of cm.
(part 2 of 2)
How far will it move in 3.4 y?
Answer in units of cm.

magnitude and direction

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

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 .
