Question

The function T(n) is defined below. Which of the following are equal to T(8)? Check all that apply.

T(n) = 4n - 5

A. 37
B. T(7) + 4
C. 27
D. T(5) + T(3)

There could be more than one answer. I know C is one of them.

Answer 1

what is \(T(7)+4\)?

Answer 2

I'm not sure. I'm still trying to figure that out.

Answer 3

how did you get \(T(8)\) ?

Answer 4

N = 8... right? I think.

Answer 5

replace \(n\) by \(8\) right

Answer 6

yea then I multiplied \[4 \times 8 - 5 = 27\]

Answer 7

ok good
now try
\[4\times 7-5+4\] and see what you get

Answer 8

That's 27 as well.

Answer 9

I don't understand how you got that.
