graph the inequality - how?

Question

graph the inequality

y (less than or equal to) -3/2x^2 - 6x - 10

Graph the assoicated parabola, plot the vertex and four additional points, two on each side of the vertex. What would the points be?

Answer 1

Find the vertex as in your other questions -b/2a and substitute in to find y. Since the graph is symmetric, pick a point to the right and left of the vertex, the same distance from it. V ( -2, -4) So now pick -3 and -1 for x and then -4 and 0 for x. Find y. Shade since its <=.
