Question

The graph of a piecewise-defined function is given. Write a definition for the function that best describes this graph. (1,3) 3 (-2,1) X -3 (0,0) 3 f(x) = if Isxs (Type the left piece of the function.)

Answer 1

to exactly function definition A relation from a set of inputs to a set of possible outputs where each input if related one output Piecewise function Definition This is a that function which is defined on a intervals sequence of intervals Example f(x) = (x) can be written as +x. forwa J xo Halo -a भ fig.
