finding function rules

Frank works as a sales person. He earns a salary of $425 and 4% commission on his monthly sales. Write a function rule that relates his total earnings to sales and find his earnings for the month, if his monthly sales are $4000. => $600 or $585 or $575 or $745..

Find a rule for the function ( f + g )( x ), if f ( x ) = 8 x - 2 2 , g ( x ) = 3 0 2 2 - x . => ( f + g )( x ) = 2 2 ( x - 2 2 ) or ( f + g )( x ) = - 2 2 x or..

Find the rule for the function ( f ⋅g )( x ), if f ( x ) = x 2 + 4 x - 1 2 x + 2 , g ( x ) = x 2 - 4 x + 6 . => ( f ⋅g )( x ) = ( x - 2) 2 or ( f ⋅g )( x ) = ( x + 2) 2 or ( f &sdot..

Find the rule for the function ( f - g )( x ) f ( x ) = 5 x x - 7 , g ( x ) = 1 1 4 3 x - 2 1 . => ( f - g )( x ) = 5 x - 3 8 x - 7 or ( f - g )( x ) = 5..

Find the rule for the function ( f ÷ g )( x ) if f ( x ) = 5 x x 5 - 1 1 x 2 , g ( x ) = 2 5 x x 3 - 1 1 . => ( f ÷ g )( x ) = - 1 5 x 2 or ( f ÷ g ..

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..
