Let f(x)=100−10+e−0.1x. What is f(−6)? Enter your answer, rounded to the nearest tenth, in the box.

Answer 1

This is just a calculator problem. Plug in x = -6:

f(-6) = 100 - 10e^-0.1(-6)

f(-6) = 100 - 10e^0.6

f(-6) = 100 - 10(1.8221188)

f(-6) = 100 - 18.221188

f(-6) = 81.778812

Round to 81.8
