A student is measuring the circumferences of pine trees for an experiment. She measures 50 trees using a ruler that measures to the nearest centimeter.

Which statement describes a change that could help improve the results of

her experiment?

Her measurements will be more accurate if she uses a cloth tape

measure instead of a ruler.

Explanation: (apex)

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 .
