Question 237212: I am not really understanding how to do this,
I need to evaluate each of the functions below at x= 1,2,4,8, and 16. Plot the graph of each function. Classify as linear, quadratic, polynomial, exponential or logarithmic and explain the reasons for your classifications.
f(x) = 3x - 2

You can put this solution on YOUR website! I need to evaluate each of the functions below at x= 1,2,4,8, and 16. Plot the graph of each function. Classify as linear, quadratic, polynomial, exponential or logarithmic and explain the reasons for your classifications.
f(x) = 3x - 2
-------------
Sub each value for x and find f(x). You can let y = f(x) to graph it.
y = 3x-2
--------
x...y
------
1...1 --> (1,1)
2...4 --> (2,4)
4...10 --> (4,10)
8...22
16..46
---------
If you plot the points, you'll see it's a straight line thru all of them.
Line --> linear equation.
