How many x intercepts appear on the graph of this polynomial function? f(x)=x^4-5^2. 1 x intercept 2 x intercepts 3 x intercepts 4 x intercepts

(23*2)-12=x     x=34

step-by-step explanation:

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.
