Step-by-step explanation:
<u>Composite Function </u>
Given f(x) and h(x) real functions, the composite function named is defined as:
It can be found by substituting h into f.
We are given the functions:
It's required to find
As defined above:
Thus:
Find h(2):
h(2)=0
Now:
Let the two numbers be x and y, then,
xy = -12 . . . (1)
x + y = -10 . . . (2)
From (2), x = -10 - y . . . (3)
Putting (3) into (1), gives
(-10 - y)y = -12
-10y - y^2 = -12
y^2 + 10y - 12 = 0
Therefore, the two numbers are
and 
xy = -12 . . . (1)
x + y = -10 . . . (2)
From (2), x = -10 - y . . . (3)
Putting (3) into (1), gives
(-10 - y)y = -12
-10y - y^2 = -12
y^2 + 10y - 12 = 0
Therefore, the two numbers are
