for the next one it's asking for h(2/3) but you can't use a negative for absolute value right? or is it ?

@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\[h(\frac{2}{3})=5\frac{\frac{  2}{3}}{\frac{2}{3}}=5\frac{\frac{2}{3}}{\frac{2}{3}}\]

Aylin Group TitleBest ResponseYou've already chosen the best response.1
Ahh, 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.

If \[a \ge 0\]then\[h(3a)=5\]and if\[a < 0\]then\[h(3a)=5\]

what do i have to do to know if a>0 ?
 one year ago

Shido88 Group TitleBest ResponseYou've already chosen the best response.0
how did you get h(3a)= 5 ? do you just cancel out the 3a ?
 one year ago

Aylin Group TitleBest ResponseYou've already chosen the best response.1
Yeah.\[5\frac{3a}{3a}=5\]
 one year ago

Shido88 Group TitleBest ResponseYou've already chosen the best response.0
so if it was h(a2) would the final answer be 5 anyway ?
 one year ago

Aylin Group TitleBest ResponseYou've already chosen the best response.1
Either 5 or 5, depending on a.
