F(1)= (what belongs here)

1

Step-by-step explanation:

f(1) is simply the value of f(x) when x = 1. Therefore, looking at the graph, when x = 1, f(x) = 1.

Step-by-step explanation:

f(1) is the "value of the function f when the input "x" is 1.  We look at the diagram and find (or draw) a vertical line through x = 1.  At what y value does this line intersect the graph?  I see y = f(1) = 1.  ( Look for the point (1, 10).  )

the answer is c

hope this !

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
