Question

G(n) = 2n + 5; find g(-1)

Answer 1

Solving g(n)=2n+5 by putting n=-1 we get g(-1)=3

Explanation:

We are given g(n)=2n+5

We need to find g(-1)

For finding g(-1) put n=-1 in g(n)=2n+5

`g(n)=2n+5\\Put \ n=-1\\g(-1)= 2(-1)+5\\g(-1)=-2+5\\g(-1)=3`

So, Solving g(n)=2n+5 by putting n=-1 we get g(-1)=3
