Respuesta :

f(1) is the value of f(x) when x = 1

So here f(1) = 5.

Answer:

5

Step-by-step explanation:

The given table shows the relation between the independent variable x, and its image f(x). Each pair of the table represent an input and an output, that is, to each x-value there's one f(x)'s value.

So, we observe that when [tex]x=1[/tex], [tex]f(1)[/tex] is 5, because is the image of [tex]x=1[/tex]
