Question 57163
sketch the graph of the function: f(x)=3x+1
This is a linear function.  f(x) is name of the function, but you graph it just like you would y=3x+1.  f(x)=y on the cartesian graph.
Find f(0)
f(0)=3(0)+1
f(0)=0+1
f(0)=1  Plot (0,1)
Find f(1)
f(1)=3(1)+1
f(1)=3+1
f(1)=4  Plot (1,4)
Connect the points and you have a line that looks like:
{{{graph(300,200,-10,10,-10,10,3x+1)}}}
Happy Calculating!!!
