f(a) 14 years ago

Answer 2

Where is the Expression INSIDE the abs-brackets small - this is the way to solve... follow it

Answer 3

The number itself will NOT be small....

Answer 4

those are aboslute value signs

Answer 5

Yes, of course. Once again: think where [for which x] the Expression inside will be small.

Answer 6

how can i solve this?

Answer 7

By trial and error, perhaps.
Example:
f(4) = |3(4) - 17| = |12-17| = |-5| = 5 > 4, so 4 is NOT the answer.

Answer 8

hmmmmmmm.........

Answer 9

Or you can solve it in fact.
f(a) < a
|3a - 17| < a
-a < 3a-17 < a
Solve a.

Answer 10

You'll get something like __ < a < __
And you can get all values of a satisfying the inequality.
