Question

If f(x) = x + 5, what does f(8) represent?

A. The value of x when (x + 5) = 8

B. The value of 8f(x) when x = 8

C. The value of f(x) when (x + 5) = 8

D. The value of (x + 5) when x = 8

Answer 1

@KamiBug

Answer 2

D because it's telling you to plug in 8 to the problem

Answer 3

what do u think ?

Answer 4

It is the value of (x + 5) when x = 8

Answer 5

value of (x + 5) when x = 8

Answer 6

basically x =8 like
f(x) =x + 5
f(8) =8+5

Answer 7

so D ?

Answer 8

8 represents what you should substitute x for...
f(8) = 8 + 5
f(8) = 13
So yes...I would say D.

Answer 9

Yeah D, @IndianBoyNiko

Answer 10

A sequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. If f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence?

A. f(1) = 2 and f(n) = f(n - 1) + 4; n > 1

B. f(1) = 4 and f(n) = f(n - 1) + 2n; n > 1

C. f(1) = 2 and f(n) = f(n - 1) + 4n; n > 1

D. f(1) = 4 and f(n) = f(n - 1) + 2; n > 1
