If f(x) = x + 5, what does f(8) represent? the value of x when (x + 5) = 8 the value of 8f(x) when x = 8 the value of f(x) when (x + 5) = 8 the value of (x + 5) when x = 8

f(8) represents the value of (x + 5) when x = 8 and the value of f(8) is 13 .

Step-by-step explanation:

As given in the question be as follow

f(x) = x + 5

put  x = 8  in the  expression f(x) = x + 5 .

Thus the expression becomes

f(8) = 8 + 5

     = 13

f(8) = 13

Therefore f(8) represented the value of (x + 5) when x = 8 and the value of f(8) is 13 .
