y The graph of a rule connecting x and y is shown. From the graph, when x is -1, what is y? x
The rule is y = x3 + 2x2 8x y If x = -4, what is x3 + 2x2 8x? When is x3 + 2x2 8x = 16? x
The rule is y = -x2 - 2x + 3 y Solve -x2 - 2x + 3 = 4 Solve -x2 - 2x + 3 = 0 x
The rule is y = -x2 - 2x + 3 y What is the maximum value of -x2 - 2x + 3? x
y = 3 2x y = 2x + 1 Here are the graphs of 2 rules. When does 3 2x = 5 ? When does 2x + 1 = 0 ?
y = 3 2x y = 2x + 1 Here are the graphs of 2 rules. When does 3 2x = 2? When does 2x + 1 = 2? When does 3 2x = 2x + 1 ?
