Let f (x) = 6-2+2e-0.3x. What is f (-4) ?

f (-4) = 10.636

Step-by-step explanation:

In this problem we need to substitute and add together the remaining terms

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

If we simplify

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

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

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

e = 2.718

f (x) = (4) + 2 (2.718) - 0.3x

f (x) = (4) + 5.436 - 0.3x

f (x) = 9.436 - 0.3*x

We just need to substitute for x = - 4, to get f (-4)

f (-4) = 9.436 - 0.3 * (-4)

f (-4) = 9.436 + 1.2

f (-4) = 10.636

Answer: 1.3
