Just add their right sides:
f(x) + g(x) = "right side of f(x)" + "right side of g(x)"
f(x) + g(x) = (16-x²) + (4-x)
Now simplify:
f(x) + g(x) = 16 - x² + 4 - x
f(x) + g(x) = 20 - x² - x
Arranging in descending order
f(x) + g(x) = -x² - x + 20

You can put this solution on YOUR website!
Let f(x) = 16 - x^ ….do you have here or ?
if you have , then we have:
