Function - We consider two sets A and B. We form the Cartesian Product, we form relations. From all the relations, we can select a few which satisfy the rule that each element of the set A is related to only one element of the set B. When a relation satisfies this rule..

Which of the following function rules satisfies the graph? => Output = Input 2 or Output = Input + 2 or Out put = 2 × Input or Output = Input..

(1) Let the given function be f (x) on the real number line R. (2) Differentiate the function f(x) with respect to x and equate it to zero i.e., put f '(x) = 0. Solve for x. These values of x which satisfy f '(x) = 0 are called Critical values of the function (3) Arra..

Which of the following function rules best suits the graph? => y = 4 + 2 x or y = 6 - 2 x or y = 7 + 3 x or y = - 5 + 3 x..

Choose a rule for the linear function in the table shown. => f ( x ) = 1 2 x - 1 or f ( x ) = - 2 x - 1 or f ( x ) = 2 x + 3 or f ( x ) = 2 x + 1..
