Answer
a) The $y$-intercept is $(0,0)$; the $x$-intercepts are the points on the line segment from $(-1,0)$ to $(2,0)$.
b) The graph is not symmetric with respect to the $x$-axis, $y$-axis nor the origin.
Work Step by Step
a) The intercepts can be found at the intersection of the blue graph and the axes. Here, the graph intersects both axes, the y-axis intercept is at: $(0,0)$; the x-axis intercept is a line from $(-1,0)$ to $(2,0)$
b) If a graph is symmetric with respect to the $x$-axis then if the point $(x,y)$ is on the graph, then $(x,-y)$ is also on the graph; the graph is not symmetric with respect to the $x$-axis.
If a graph is symmetric with respect to the $y$-axis then if the point $(x,y)$ is on the graph, then $(-x,y)$ is also on the graph; the graph is not symmetric with respect to the $y$-axis.
If a graph is symmetric with respect to the origin then if the point $(x,y)$ is on the graph, then $(-x,-y)$ is also on the graph; the graph is not symmetric with respect to the origin.
