how to graph a supply and demand curve

The scatter plot gives a relationship between demand and price of consumer goods. What trend does the graph follow? => No trend or Negative trend or Positive trend..

What is the equation of the curve in the graph? => y = 3(2) t or y = 13(2) t or y = 2(3) t or y = 13(3) t..

The graph depicts the relation between the price and the supply of an item. What trend does the graph follow? => no trend or data is insufficient to decide the kind of trend or positive trend or negative trend..

Curve Sketching - The graph of a given function gives a visual presentation of the behaviour of the function involving a study of symmetry, rise and fall, region of existence, passage through specific points etc. The following points are helpful to trace the curve..

The graph drawn between the temperature of a body and time is known as cooling curve. The slope of the tangent to the curve at any point gives the rate of fall of temperature. If rate of fall of temperature is plotted against excess temperature, we get a straight line ..

The solubility of a given solute in water, as done above, can be determined at many different temperatures, say 0 o C, 10 o C, 20 o C,..100 o C. The result so obtained can be plotted on a graph by taking temperatures along the X-axis, and solubility along the Y-axis. By joining the points..

Write the equation of the curve in the graph. => y = - x 2 or y = x 2 or y = x 2 - 1 or None of the above..

The growth rate of an individual at different periods of life can be represented in a growth curve by plotting the weight of individual at different time intervals (in years) on a graph paper. For example a human baby can be weighted from birth till adult hood when growth stops...

Which model best represents the decay curve shown in the graph? => y = 1 2 t + 50 or y = 2(0.5) t or y = 50(1.5) t or y = 50(0.5) t..
