Find the vertex and intercepts for each quadratic function and sketch its graph.


# 49.   y = x^2 - 4x - 12


# 50.  y = x^2 + 2x - 24


# 53.  Y = - x^2 + 2x + 3


# 54.   y = - x^2 - 3x - 2


Use the discriminate to determine whether each quadratic polynomial can be factored, then factor the ones that are not prime.


# 59.   8x^2 - 10x - 3

Solve each inequality. State the solution set using interval notation and graph it.
