Which kind of mathematical calculations are most useful in determining the components of a vector in two perpendicular directions when only the angle of the resultant vector is known?
O A. fraction and percent
OB. sine and cosine
c. range and average
OD. addition and subtraction

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 .
