piecewise functions with quadratics worksheet
carefully graph each of the following. plot each piece separately. use t-charts if needed. identify the domain and range. then, evaluate the graph at the specified domain values.

carefully graph each of the following. identify whether or not the graph is a function. then, evaluate the graph at the specified domain value. you may use your calculators to you graph, but you must sketch it carefully on the grid!
x + 5
4. f(x)=x2 +2x+3
function? yes or no
f (3)= f (−4)= f (−2)=
x < − 2 x≥−2
x2 x ≤0 5. f (x ) =
−x2+4 x> 0
function? yes or no
f (−4)= f (0)= f (3)=
2x+1 x≥1 6. f(x)=x2 +3 x< 1
function? yes or no
f (−2)= f (6)= f (1)=
