Answer:
We have been given a table:
x: -5 -4 -3 -2 -1 0 1 2 3
f(x):-11 -3 5 13 21 29 37 45 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) 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).
