Question

i need help with a graph function http://i.imgur.com/gdQ8DUa.png its l
on the graph portion of it

Answer 1

so look at it this way... if you draw tangents on the curve... where would they have positive slopes... x > ?

Answer 2

Assuming that's an I:

It's -1. Relative minimum generally can be identified as the peak of the downwards-pointing hills of an equation. To be more concise, if we draw the slope equation at a relative min/max, the slope of that slope equation is 0.

Assuming that's an L:
The function is neither. if we take the portion from [0, infinity], we get the quadratic equation as (x - 2)(x - 4). If we expand this, we get x^2 - 6x + 8. So if we plug in -x, we don't get neither f(x) (due to 6x) or -f(x) as the result (due to x^2).
