Which set of graphs can be used to find the solution set to 3 log2(x + 4) < 6?
Answer
A
On a coordinate plane, a dotted line is at y = 6. Everything above the line is shaded. A dotted line curve approaches x = negative 4 in quadrant 3, and curves up through (negative 3, 0) and (0, 6). Everything above the curve and to the right of x = negative 4 is shaded.
B
On a coordinate plane, a dotted line is at y = 6. Everything above the line is shaded. A dotted line curve approaches x = negative 4 in quadrant 3, and curves up through (negative 3, 0) and (0, 6). Everything below and to the right of the curve is shaded.
C
On a coordinate plane, a dotted line is at y = 6. Everything below the line is shaded. A dotted line curve approaches x = negative 4 in quadrant 3, and curves up through (negative 3, 0) and (0, 6). Everything below and to the right of the curve is shaded.
D
On a coordinate plane, a dotted line is at y = 6. Everything below the line is shaded. A dotted line curve approaches x = negative 4 in quadrant 3, and curves up through (negative 3, 0) and (0, 6). Everything above the curve and to the right of x = negative 4 is shaded.
