Let f(x)=6/-2+2e^-0.3x. what is f(4)? enter your answer rounded to the nearest tenth

pochemuha

The value of the function f(x)=6/-2+2 $e^{-0.3x}$ at x=4 after rounded to the nearest tenth is -2.4.

Given Function of x : f(x)=6/-2+2 $e^{-0.3x}$

The given function showing the relationship between x and f(x) is f(x)=6/-2+2 $e^{-0.3x}$ where e is exponential and we have to find the value of f(4) by just putting the value of x=4 in the given function and round to the nearest tenth means replacing a number with an approximate value.

f(4)=6/-2+2 $e^{-0.3*4}$ ( The value of e is 2.7812)
