There is a table of values for the function f. They read: x=3, f(x)=4 x=4 f(x)=5 x=5 f(x)=6 x=6 f(x)=3 x=7 f(x)=5 x=8 f(x)=7 What is the value of 2f(5)-f(4)? I did this wrong obviously, but what I did was figure out the function of five from the table (4), and multiplied that ...

**Graphing and Exponential Function**

I really don't understand on graphing exponential function. Can anyone help? It is difficult to answer this. Make a table of values, say. y x for the function y=e^x fill in the table, plot the points.
