do you know how the absolute value works?
the quantity in the absolute value can be either > 26 or <-26
solve both of them
sorry I just saw this, one second
isnt it >26
im really confused
the function is larger than 26 for those shaded areas
okay, but if i look at the answer choices, 26 is not on one of the answer choices
right, you have to solve for the intervals of the shaded area if the absolute value is greater than a number, you will get an OR statement with two solution intervals... The absolute value function is just a distance from zero, if this distance is greater than, you will have two solutions Like if absolute value of x is greater than 2, you will get x>2 OR x <-2, both those are the solutions for all distances greater than 2 from zero
ohh okay that makes sense
so if i I2x+10I>26 and subtract 10 on both sides it will give me I2xI>16 And then divide both sides by 2 i will get IxI>8
If the absolute value is Less Than some value, say 'a', the solution will be in the form of an AND statement -a < abs( function) < +a single solution region between + and - a
okay I think I got it! Thank you!
k, yeah the third one
Here this is straight forward if you need to review this http://www.purplemath.com/modules/absineq.htm
