Question

p(n)=3n+5 ; Find p(n+3)

A. p(n-2)=3n+14

B. 3n+14

C. p(n-2)=3n+8

D. p(n-2=17n

E. p(n-2)=3n+11

Answer 1

p(n) = 3n + 5

To find p(n+3), replace n by n+3.

So, p(n+3) = 3(n+3) + 5 = 3n + 9 + 5 = 3n + 14 The answer is choice "B".

Answer 2

p(n) = 3n + 5

p(n+3) = 3(n+ 3) + 5

None of the choices match. Review your post..
