three variable function

A function is described by the equation f ( x ) = 3 x + 5. The replacement set for the independent variable is {1, 2, 5, - 7}. Which of the following is contained in the corresponding set for the dependent variable? => - 1 or - 16 or 26 or - 8..

A function is described by the equation f ( x ) = 2 x + 1. The replacement set for the independent variable is {0, 2, 3, 4}. Which of the following is contained in the corresponding set for the dependent variable? => 9 or 2 or 3 or 15..

Let S be a sample space associated with a given random experiment. A real valued function X which assigns to each w i S, a unique real number, X( w i ) = x i is called a random variable . Two types of random variables are 1. Continuous random ..

Limits on the variables in the objective function are called _______. => Extremes or Vertices or Restrictions or Objectives..

Example: A rubber ball dropped from a certain height (h 1 ) on reaching the ground bounces up to a height less than the initial one (h 2 ). It continues to bounce but the height to which it rises keeps decreasing (h 3 , h 4 ). The distance covered by the ball in unit time decreases. The ..

Normally metals donate electrons from their valence shell so as to form positively charged ions such that the charge on the ion is equal to its electropositive valency. However, in transition elements, an atom loses electrons from the shell next to the valence shell (penultimate shell). In such a s..

1. Activator of enzymes like oxidases, peroxidases, dehydrogenase, kinases and dicarboxylases. 2. Maintenance of lamellar structure of chloroplast. 3. Essential for photolysis of water and evolution of oxyg..

1. For the formation of sulphur containing protein. 2. It is a component of two vitamins. (B and Biotin). 3. In onion and garlic, sulphur occurs in the form of glucosides, which provide characteristic odour to these plants. 4. Sinigrin and sinalbin are glucosides in black and white mustar..

1. Iron is a constituent of cytochromes, ferredoxin, nitrogenase, catalase peroxidase, hematin etc. 2. Essential for the development of chloroplast and chlorophyll. 3. Many of iron containing enzymes take part in electron transfer in both photosynthesis and respiration. 4. Structure of po..

It is the most abundant cation in plants. 1. Required for the metabolic activities of cells in young growing parts like root tips and young leaves but seeds are an exception. 2. Essential for the functioning of about forty enzymes which take part in glycolysis, Kreb's Cycle, photosynthesi..
