How do you find the axis of symmetry, graph and find the maximum or minimum value of the function #y=2x^2-7x-8#?
y intercept is -8
It is a positive
Put this into the equation to find the y coordinate
Construct a table of values, putting values of x into the equation to get the relevant y values in order to plot the graph.
Use values between -2 and 2 for x
