Question 1109971
.
Hey,  


there is &nbsp;<U>COMMON UNDERSTANDING</U>&nbsp; at this forum, &nbsp;that 



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;making calculations is the student's &nbsp;DUTY &nbsp;and &nbsp;PRIVILEDGE.



The tutors &nbsp;<U>DO NOT MAKE</U>&nbsp; calculations for you &nbsp;(or instead of you).



So, &nbsp;substitute &nbsp;(-3) &nbsp;instead of &nbsp;x&nbsp; into the function and calculate.
