Dalila plans an experiment to examine plant growth. She made a table to record her results. What addition to her table would most improve her experimental investigation?

a row in which no fertilizer is used
a row in which 12 grams of fertilizer are used
a column that shows how the dependent variable changes
a column that shows how the independent variable change

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 .

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
