Answer:
We have been given a table:
x: -5 Â -4 Â -3 Â -2 Â -1 Â 0 Â 1 Â 2 Â 3
f(x):-11 Â -3 Â 5 Â 13 Â 21 Â 29 Â 37 Â 45 Â 53
Part (a) the function is linear the line is a straight line from two points given above
Function is: y+11=8(x+5) Â from point (-5,-11)
          y=8x+29
Part (b) adding 8 each time x increases by 1
Part (c) the function is y =8x+29
To find y-intercept put x =0 we get y=29
So, y-intercept is (0,29).
