CPM Homework Help : A2C Problem 7-159

Graph each system below and shade the solution region.

$y ≥ x^2 - 4$
$y < -3x + 1$

$y < 2x + 5$
$y ≥| x + 1 |$

Hint (a):

Graph each function and decide if the lines should be dashed or solid. Then shade the appropriate region.

Graph (a):

Upward solid parabola, vertex at (0, comma negative 4), & dashed line, passing through the points (0, comma 1), & (negative 2, comma 1), intersect and divide the plane, into multiple regions. The inside of the parabola, shaded pink, area below & left of line, shaded blue. Area inside parabola, & left of the line, shaded purple.

Hint (b):

Graph each function and decide if the lines should be dashed or solid. Then shade the appropriate region.

Graph (b):

Upward solid V, vertex at (negative 1, comma 0), & dashed line, passing through the points (negative 3, comma negative 1), & (negative 1, comma 3), intersect & divide the plane, into multiple regions. Area inside V, shaded blue, area right of line, shaded pink, area inside V & right of line, shaded purple.
