Find the domain and range of these functions. a) the function that assigns to each pair of positive inte- gers the maximum of these two integers b) the function that assigns to each positive integer the number of the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 that do not appear as decimal digits of the integer c) the function that assigns to a bit string the number of times the block 11 appears d) the function that assigns to a bit string the numerical position of the first 1 in the string and that assigns the value 0 to a bit string consisting of all os

See below

Step-by-step explanation:

a)

Domain: the cartesian product of integers ZxZ

Range: the integers Z, for every p in Z is the image of (p, p-1)

b)

Domain: the positive integers Z+

Range: the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} obviously, f(1)=9, f(12)=8, f(123)=7,...,f(123456789)=1 and f(1234567890)=0. So, every number in {0,1,...,9} is the image of some positive integer.

c)

Domain: all the bit strings. Since any real number can be written as a bit string in the binary system, the domain is actually the set R of real numbers.

Range: a bit string can have 0 or 1 or 2 or more blocks “11”, so the range is the set N of natural numbers including 0.

d)

Domain: all the bit strings (the real numbers as in c).  

Range: the natural numbers N plus 0

step-by-step explanation:

should you really be posting this isn't math boi.

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
