X- intercept is the point at which graph of function cuts the x - axis. So X intercept is at (1, 0) and (3, 0)
Y- intercept is the point at which graph of function cuts the Y- axis, So y intercept is at (0, 3)
Graph is positive in interval x ≤ 1 and x ≥3
And graph is negative in interval 1 ≤ x ≤ 3
Since, The x intercept is the point where the line crosses the x axis and The y intercept is the point where the line crosses the y axis.
By observing given graph
X intercept is at (1, 0) and (3, 0)
Y intercept is at (0, 3)
By seeing graph, it is observed that graph is positive in interval x ≤ 1 and
x ≥3 and graph is negative in interval 1 ≤ x ≤ 3
