1) One year after a tree is planted, the tree is 3.5 ft tall. Each year, the tree grows 1.5 ft.
What function, written in sequence notation, models the height of the tree n years after it is planted?
an=1.5n+3.5
an=3.5n+1.5
an=1.5n+2
an=5n+1.5
2) What function equation is represented by the graph?
f(x)=−1/2x−1
f(x)=−2x−1/2
f(x)=−x−2
f(x)=−2x−1
3) Earl mows lawns one weekend. He earns $12 for each lawn that he mows. He spends $40 on gas and other supplies.
What function equation represents Earl's profit from mowing x lawns?
f(x)=12x+40
f(x)=40x−12
f(x)=12x−40
f(x)=40x+12
4) What function equation is represented by the graph?
f(x)=−1/4x−3
f(x)=1/4x−3
f(x)=−4x−3
f(x)=1/4x+3
