A cat runs 31 m east and then turns around and runs 30 m west. What is the cat's total distance? If your final answer is in the direction of west or south indicate this with a negative
sign

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

i think its c if i'm wrong

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 .
