Which function is positive for the entire interval left bracket negative 3 comma negative 2 right bracket ?
Answer
A
Image with description A coordinate plane with a cubic curve. The x-axis is labeled from negative 4 to 4 in increments of 1 and the y-axis is labeled from negative 8 to 8 in increments of 2. The curve starts in the third quadrant near the point 0 comma negative 8, rises steeply through the origin, reaches a local maximum at approximately 0 comma 6, descends to a local minimum at approximately 2 comma 4, and then rises steeply into the first quadrant.
B
Image with description A coordinate plane with a parabola opening upward. The x-axis is labeled from negative 3 to 7 in increments of 1 and the y-axis is labeled from negative 4 to 4 in increments of 1. The parabola has its vertex at 2 comma negative 3, passes through the points negative 1 comma 0 and 5 comma 0, and extends upward through the second and first quadrants.
C
Image with description A coordinate plane with a parabola opening upward. The x-axis and y-axis are labeled from negative 4 to 4 in increments of 1. The parabola has its vertex at 0 comma negative 3, passes through the points negative 3 comma 0 and 3 comma 0, and extends upward through the second and first quadrants.
D
Image with description A coordinate plane with a cubic curve. The x-axis is labeled from negative 3 to 3 in increments of 1 and the y-axis is labeled from negative 7 to 3 in increments of 1. The curve starts in the third quadrant near the point negative 2 comma negative 3, rises to a local maximum at approximately 0 comma 2, descends steeply to a local minimum at approximately 1 comma negative 7, and then rises into the fourth quadrant.
