Are the following set of ordered pairs functions ? If so examine whether the mapping is injective or surjective .
{(x,y) : x is a person, y is the mother of x }

Let A = {x: -1lexle1} = B for each of the following functions from A to B. Find whether it is surjective, injective or bijective (i) f(x) = (x)/(2) (ii) g(x) = |x| (iii) h(x) = x|x| (iv) k(x) = x^(2) (v) l(x) = sin pi x

Examine whether the following statements are true or false : phi sub {x, y, z}

Express the following functions as set of ordered pairs and determine their range. f: x rarr R, f(x)= x^(3) + 1 , where x= {-1, 0, 3, 9, 7}

Examine the following functions for continuity. f(x)= x-5

Plot the points corresponding to ordered pairs of (x, y) given in the following table :

Examine the following functions for continuity. f(x) = |x-5|

Solve the following pair of equations : 4x+y=3xy and 8x+3y=7xy .

State whether each of the following statements are true or false. If the statement is false, rewrite the given statement correctly If A and B are non-empty sets, then A xx B is a non-empty set of ordered pairs (x,y) such that x in A and y in B
