Best ResponseYou've already chosen the best response.0for the next one it's asking for h(2/3) but you can't use a negative for absolute value right? or is it ?

Best ResponseYou've already chosen the best response.0umm why over 5 ? isn't it over 2/3 ?

Best ResponseYou've already chosen the best response.1@Shido88 Sorry, I got distracted. Back now. Absolute value as a function either leaves the thing inside of it alone if it is 0 or positive, or multiplies it b negative 1 if it is negative. So x=x IF x is greater than or equal to 0, and x = x IF x is less than 0. So for h(2/3) you would have\[h(\frac{2}{3})=5\frac{\frac{  2}{3}}{\frac{2}{3}}=5\frac{\frac{2}{3}}{\frac{2}{3}}\]

Best ResponseYou've already chosen the best response.1Hmm, looks like the negative signs didn't display properly... Well, the 2s that are shifted way over to the right are supposed to have negative signs in front of them.

Best ResponseYou've already chosen the best response.0so basictly anything negative inside the absolute value will turn into positive ?

Best ResponseYou've already chosen the best response.0and once u turn the negative into positive then the absolute value sign goes away ?

Best ResponseYou've already chosen the best response.1Ahh, well this depends on if a is positive or not. :P Find the answer for if a is positive, and then the answer for if a is negative. Then you say which one it is based on a.

Best ResponseYou've already chosen the best response.0how did you get h(3a)= 5 ? do you just cancel out the 3a ?

Best ResponseYou've already chosen the best response.1Yeah.\[5\frac{3a}{3a}=5\]

Best ResponseYou've already chosen the best response.0so if it was h(a2) would the final answer be 5 anyway ?
