Question

F(n)=n-5 and g(n) =4n+2 find (f+g) (-8)?

Answer 1

To find (f+g)(-8), substitute -8 into the expressions for f(n) and g(n), and then add the results together. The result is -43.

Step-by-step explanation:

To find (f+g)(-8), we need to substitute -8 into the expressions for f(n) and g(n) and then add the results together.

Given that f(n) = n - 5 and g(n) = 4n + 2, we can substitute -8 into both expressions:

f(-8) = (-8) - 5 = -13

g(-8) = 4(-8) + 2 = -30

Now, we can add the results together to find (f+g)(-8):

(f+g)(-8) = f(-8) + g(-8) = -13 + (-30) = -43
