Answer 1

Answer #1

Graph 1 that is x(t) graph is a even function graph because even function graph is symtric about co ordinate axis . Also if postive side of graph is mirror image of negative side then this is called a even function graph.

Graph2 that is y(t) is neither odd nor a even function graph because this is neither symmetric nor antisymmetric about co ordinate axis. Neither mirror image nor inverted mirror image. So this graph is neither odd nor even function graph.

Graph3 that is z(t) is a odd function graph because it is antisymmetric about co ordinate axis and left side of graph is inverted mirror image of right side of the graph. So this is a off function graph.

Thankyou
