Answer:
-13°F is the change in temperature.
Step-by-step explanation:
The change in temperature is,
→ -1 + x = -14
→ x = -14 + 1
→ [ x = -13 ]
Hence, -13°F is the change.
7 is the slope intercept form of this equation. i hope this helps.
Wherever you see x in f(x), substitute in g(x).
So f(g(x)) = (g(x))² + 3
But what's g(x)?
g(x) = (x + 2)/x
So the answer would be ( (x+2)/x )² + 3
Which could simplify to (x+2)² / x² + 3 = (x² + 4x + 4)/x² + 3
Sorry if I made a mistake somewhere.
Hope this helped!
