Question 1128799: Evaluate the function. (Round your answer to four decimal places.)
f(x) = −5e^x − 1, for f(−2)
*I subsitiuted (-2) for x, which transformed the equation into -5^(-2)-1. The answer incorrectly resulted in .0080. Can someone demonstrate the correct method that should be used. thanks

f(-2)=-5*e^(-2)-1
e^(-2)=1/e^2=0.1353
-5e^(-2)-1=-1.6767, rounding at the end
