Prepare a table of values for the relation:
y = 2x² - 4x - 7, for values of x from -2 to 4.
(b) Using a scale of 2cm to 1unit on the x-axis and 2cm to 2units on the y-axis, draw the graph of:
y = 2x² - 4x - 7.
(c) From your graph, find the roots of the equation:
2x² - 4x - 11 = 0.
(d) From your graph, find the minimum value of:
y = 2x² - 4x - 7.
(e) Determine the equation of the line of symmetry of the curve.?
