Let f (x) = 6-2+2e-0.3x.

What is f (-5) ?

Enter your answer, rounded to the nearest tenth, in the box.

f (-5) = 10.9

Step-by-step explanation:

We know the the function is

f (x) = 6-2+2e-0.3x

We group terms

f (x) = (6-2) + 2e-0.3x

f (x) = (4) + 2e-0.3x

We substitute the value for e (Euler's number)

f (x) = (4) + 2 (2.7183) - 0.3x

We add together

f (x) = (4) + 2 (2.7183) - 0.3

f (x) = (4) + 5.4366 - 0.3x

f (x) = 9.4366 - 0.3x

We substitute x = - 5

f (-5) = 9.4366 - 0.3 (-5)

f (-5) = 9.4366 + 1.5

f (-5) = 10.9366

f (-5) = 10.9
