Find the vertex of y=x

Step-by-step explanation:

The x-coordinate of the vertex can be found by the formula − b 2 a, and to get the y value of the vertex, just substitute − b 2 a, into the Finding Vertex from Vertex Form It's called 'vertex form' for a reason! The vertex is just (h,k) from the equation.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
