Define a function as a set of ordered paris.

Define a function as a set of ordered pairs.

Write the following relations as the sets of ordered pairs : A relation R defined on the set A={2,3,4,5,6} by aRbrArr|a-b| is divisible by 3.

Let A={1,2}andB={2,4,6}."Let "f={x,y):x""inA,yinBandandygt2x+1} . Write f as a set of ordered paris. Show that f is a relation but not a function from A to B.

Write the following relations as the sets of ordered pair: A relation R on the set {0,1,2,;10} defined by 2x+3y=12

Write the following relation as the set of ordered pair: A relation R on the set {0,1,2, ddot, 10} defined by 2x+3y=12.

Let the functions f and g be defined by, f={(1,2),(2,3),(3,4),(4,1)} and g={(2,-1),(4,2),(1,-2),(3,4)} Show that, (g o f) is defined but (f o g) is not defined . Also find ( g o f) as set of ordered pairs.

Define a function as a correspondence between two sets.

Define a function as a correspondence between two sets.

Let f be a function defined by f:xto5x^(2)+2,x in R (i) Express f as a set of ordered pairs using set builder notation. (ii) Is f a one-one function (iii) Find the image of 3 under f (iv) Find x such that f(x)=2

The number of function that can be defined from the set A = { a,b,c,d} into the set B= {1,2,3} is equal to
