Answer:
f(x) = -8(4)x
Step-by-step explanation:
The reflection of the point (x,y) across  the x-axis is the point (x,-y). 
Having said this, to reflect the function y=g(x) = 8(4x) over the x-axis, we just need to evaluate the equation in the point: (x,-y).
y = 8(4x) ⇒ -y = 8(4x) ⇒ y = -8(4x)
Then f(x) = -8(4x)
Attached you will find the graph of g(x) (blue) and f(x) (red),

Answer:
-75
Step-by-step explanation:
Let us consider the first  odd number to be 'x'.
 Thus: 
- 1st odd number: x
- 2nd odd number: x+2
- 3rd odd number: x+3
According to the question, the sum of these three consecutive ODD numbers should be equal to -219
So,
x + x + 2 + x + 4 = -219
3x + 6 = -219
3x = -225
x = -75
