Answer:
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
