Hi, Can someone help me to resolve this ? I m kind of lost because of the minus in he exponant ? 

 

Given H(x) = e^-x+4  so the exponant is -x+4 

 

A. H(-2) 

 

B. H(4) 

 

C H(5) 

 

Thank you, everyone ! :)

A) h(-2)= e^(-(-2)+4) = e^(2+4) = e^6

 

B) h(4)= e^(-(4)+4) = e^(0) = 1

 

C) h(5)= e^(-(5)+4) = e^(-1) = 1/e = 0.367879441171
