function the domain is broken into pieces with a different r

function, the domain is broken into pieces, with a different rule defining the function for each piece. For a aber 1 2 3 4 f(-3.4) -4 This graph is one-to-one. This is the graph of the greatest integer function. This is the graph of the absolute value function. f(4.9) 5

Solution

This is the graph of greatest integer function
f(-3.4) = -4
f(4.9) = 4

Hence answers are:
f(-3.4) = -4
This is the graph of the greatest integer function
