elements that are contained in both sets A and B

A

intersection

20

elements contained in set A that are not contained in set B. It should be
observed that, in general, A – B != B – A

A

22
Q

A set of elements called the set X

23
Q

A set of elements called the set Y

24
Q

A ________ that associates each element of
the domain set with exactly one element of the codomain set.

A

rule of correspondence f

25
For x E X and y E Y, a function is denoted by f:X → Y or f(x) = y. (T OR F)
True
26
Two functions are not equal if they have the same domain set, the same codomain set and the same rule of correspondence.
False
27
Two functions are equal if they have the same domain set, the same codomain set and the same rule of correspondence. (T OR F)
True
28
The ____ of a function f is the set of elements in the codomain Y that are associated with some element of the domain X under the rule of correspondence f
range
29
If the codomain of a function and the range of the function are equal, then the function is said to _____
onto
30
If each element of the domain X maps to a unique element of the codomain Y, then the function is said to be _______
one-to-one
31
A function f has an ______, denoted f^-1, if and only if f is one-to-one and onto
inverse
32
For function f:X → Y one-to-one and onto, the inverse is a function f -1 :Y → X such that f -1 [f(x)] = x for all x  X (T OR F)
True
33
For m  0, the function is one-to-one and onto. Thus, it has an inverse function: x = f -1 (y) = (1/m)y – (b/m) (T OR F)
T
34
For m = 0, the function becomes y = f(x) = b. All points in the domain map to a single point in the codomain. Range of function is the set {b}. Hence, function is neither one-to-one nor onto, and no inverse function exists
T
35
For m = 0, the function becomes y = f(x) = b. All points in the domain map to a single point in the codomain. Range of function is the set {b}. Hence, function is neither one-to-one nor onto, and no inverse function exists (T OR F)
T
