then graph each function
can you show me the steps?
f(x)= I 3x-2 I
| 3x - 2 | means "absolute value of (3x - 2)"
So, f(x ) = | 3x - 2 | is an absolute value function.
To graph this function, or ANY function, you can choose values for x, and compute the corresponding values for y.
I suggest you try this approach to graph YOUR function.
Pick a bunch of values for x...
For example, you might want to use these values for x: -4, -3, -2, -1, 0, 1, 2, 3, 4
Substitute each value of x into the function definition. For example, if you use -4 for x, you'll have
f(x) = | 3*(-4) + 2 |, or
f(x) = | -12 + 2 |, or
f(x) = | -10|, or
f(x) = 10
So, when x = -4, f(x) = 10, and the point (-4, 10) is on the graph.
Do the same with the other values I suggested for x. Plot each of the points you get, and you should be able to see what the graph looks like.
