Answer:
C
Explanation:
f(X)=X/6 -2.
By observation the graph cuts the y-axis when x=0 at y=-2; this explains the last term in the equation.
However two expression has both term by substiting X =-6 in equation b and C
We see that b evaluates to y= -1; while C evaluates to -3 which parallels to the value of Out in the graph hence the answer is C
From B substituting X =-6
-(-6)/6 - 2 = 6/6 - 2 =1-2 =-1
From C substituting X = -6
-6/6. - 2 = -1 -2 =-3
