This is the first quadrant graph of an even function. On a coordinate plane, a function has four connecting parts. The first par
t is a curve facing up that goes from (0, 0) to (2.5, 9). The second part is a straight line with negative slope from (2.5, 9) to (7, 7). The third part is a straight and horizontal line from (7, 7) to (9, 7). The fourth part is a curve facing down that goes from (9, 7) through (12, 4). The function is for –9 < x < –7. The function is increasing for . The point lies on the graph of the function.
