    10 x 10 = 100
  1. Solve the equation \({ x }^{ 2 }-2x-3=0\) graphically.

  2. Solve graphically \(2{ x }^{ 2 }+x-6=0\)

  3. Draw the graph of \(y={ x }^{ 2 }+2x-3\) and hence find the roots of \({ x }^{ 2 }-x-6=0\)

  4. Draw the graph of  \(y={ 2x }^{ 2 }+x-6\) and hence solve \(2{ x }^{ 2 }+x-10=0\)

  5. A bank gives 10% S.I on deposits for senior citizens. Draw the graph for the relation between the sum deposited and the interest earned for one year. Hence find
    (i) the interest on the deposit of ` 650
    (ii) the amount to be deposited to earn an interest of ` 45.

  6. A bus travels at a speed of 40 km / hr. Write the distance-time formula and draw the graph of it. Hence, find the distance travelled in 3 hours.

  7. x 1 3 5 7 8
    y 2 6 10 14 16

    Draw the graph for the above table and hence find
    (i) the value of y if x = 4
    (ii) the value of x if y = 12

  8. Draw the Graph of xy=20,x,y,>0.  Use the graph to find y when x=5 and to find x when y=10.

  9. Draw the graph of y = 2x2 + 7x - 9.

  10. Draw the graph of y = 2x2 and hence find the roots of the equation 2x2+x-10=0.
