Determine if the given function has any points of discontinuity. Explain your reasoning.
There is a point of discontinuity at x = b because the denominator has the factor x-b.
There are points of discontinuity at both x = -b and x = b because the numerator has factors of x + b and x-b.
There is a point of discontinuity at x = b only because the factor of x-bis common to both the numerator and
denominator
There is a point of discontinuity at x = -b only because the factor of x-b is common to both the numerator and
denominator and factors out.

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.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
