Question 10 • Mathematics III

Which of the graphed functions is continuous?

Answer
A
Image with description On a coordinate plane, the scale on the x axis range from negative 8 to 8 in increments of 1, and the scale on the y axis range from negative 5 to 5 in increments of 1. The graph is comprised of 3 lines. The first line starts at the closed circle (negative 4 comma negative 3) and goes through open circle (negative 1 comma negative 2). The third line starts at the closed circle (1 comma 2) and goes to (4 comma 2).
B
Image with description On a coordinate plane, the scale on the x axis range from negative 8 to 8 in increments of 1, and the scale on the y axis range from negative 5 to 5 in increments of 1. The graph is comprised of the curve and line. The curve starts at an open circle (0 comma 0) and curves up through (negative 2 comma 4). The line starts at an open circle (0 comma 0) and goes to (6 comma 2).
C
Image with description On a coordinate plane, the scale on the x axis range from negative 8 to 8 in increments of 1, and the scale on the y axis range from negative 5 to 5 in increments of 1. The graph is comprised of a curve and 2 lines. The curve starts at the closed circle (0 comma 0) and curves up through (2 comma 4). The other line starts at the closed circle (2 comma 4) and goes to (5 comma 4). The curve and the line are connected at (2 comma 4). The other line starts at an open circle (negative 1 comma negative 1) and goes through (negative 3 comma negative 1).
D
Image with description On a coordinate plane, the scale on the x axis range from negative 8 to 8 in increments of 1, and the scale on the y axis range from negative 5 to 5 in increments of 1. The graph is comprised of a curve and 2 lines. The line starts at the closed circle (0 comma 0) and goes through (negative 3 comma negative 3). The curve starts at the closed circle (0 comma 0) and curves up through (2 comma 4). The other line starts at the closed circle (2 comma 4) and goes to (5 comma 4).
