piecewise function 
Jennifer,
State the value of f(0)and f(2) and Graph

piecewise function 
Reiny,
I will interpret you second function as
{ 4 if 1 ≤ x< 1
and to make any sense, the third function is probably
{2  x^2 if x < 1
so f(0) = 4, (fits the second function)
f(2) = 2  4 = 2
make a sketch of each graph on the same grid in pencil, then erase the part which is outside the domain.
The first is a straight line starting at (1,1) with an open circle at (1,1) and following y = 2x1
the second is a horizontal line y = 4 from 1 to 1
closed circle at (1,4) and open circle at (1,4)
third is a parabola which opens downwards and to the left of (1, 1) with (1,1) open circle.
