a) Sketch the curve y = -2x² - 4x + 6

      

a) Sketch the curve y = -2x² - 4x + 6
b) Use trapezium rule taking intervals of 0.5 units to find the area under the curve.
y = -2x² - 4x + 6 within the range -2 ≤ x ≤ 4.
c) Obtain the exact area in (b) above hence calculate the percentage error introduced by using the Trapezium rule.
