Work Step by Step

For the function f(x)=x+2, going into this, you want to think what the graph could potentially look like. To create your table, you should initially be thinking of numbers you could plug in for the "x" value of f(x). The variables used will represent the coordinate on the x-axis and the outcome will be your y-axis. f(-3)=(-3)+2 =-1 Point: (-3,-1) f(-2)=(-2)+2 =0 Point: (-2,0) f(-1)=(-1)+2 =1 Point: (-1,1) f(0)=(0)+2 =2 Point: (0,2) Coordinates Derived from f(x)=x+2: (-3,-1)(-2,0)(-1,1)(0,2)
