Which graph shows a polynomial function with a positive leading coefficient?
Answer
A
Image with description On a coordinate plane with x and y axes marked from negative 8 to 8, a polynomial graph is drawn. It passes through (negative 5 comma 8), (negative 3 point 5 comma negative 2 point 5), (0 comma 2), (3 comma negative 1 point 5), (5 point 2 comma 1) and (7 comma negative 8).
B
Image with description On a coordinate plane with x and y axes marked from negative 8 to 8, a polynomial graph is drawn. It passes through (negative 1 point 8 comma negative 8), (negative 0 point 8 comma negative 4 point 5), (0 point 8 comma negative 5 point 4) and (3 comma 3).
C
Image with description On a coordinate plane with x and y axes marked from negative 8 to 8, a polynomial graph is drawn. It passes through (negative 8 comma negative 8), (negative 4 point 5 comma 2 point 2), (0 comma 1), (4 point 5 comma 2 point 2) and (8 comma negative 8).
D
Image with description On a coordinate plane with x and y axes marked from negative 8 to 8, a parabola opening downward is drawn. It passes through (negative 4 comma negative 8) and (4 comma negative 8). It has its vertex at (0 comma 0).
