Use the graph of the function to find, f(2)

Answer with explanation:

If we describe the function, it is constant function , from, x= -8,to x= -5, and then deceases till, x=0.And, then the function increases from, x=0 to x=4.and then again behaves as a constant Function from, x=4, to x=8.

The meaning of , f(x)=y , is value taken by the ordinate , y, when value of abscissa x, is substituted in the function of any kind,which may be Logarithm, Polynomial, exponential, etc.

Or,to find, f(2), draw perpendicular, from point 2, which lie on X axis, on the graph.The point where it cuts the graph, from that point draw perpendicular on Y axis.The point where this line meets y axis, is required point.

So, f(2)=1

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
