- h(x) = f(x) + g(x) =

- h(x) = g(x) – f(x) =

- h(x) = 4g(x) =

<u>Step-by-step explanation:</u>
Here we have , f(x) = -2.5x + 12; g(x) = 21x - 28 or
.
10. Find h(x) = f(x) + g(x).

11. Find h(x) = g(x) – f(x).
⇒ 
⇒ 
⇒ 
⇒ 
12. Find h(x) = 4g(x).
⇒ 
⇒ 
⇒ 
Step-by-step explanation:
sec x − cos x
Secant is the inverse of cosine:
(1 / cos x) − cos x
Find the common denominator:
(1 / cos x) − (cos² x / cos x)
Subtract:
(1 − cos² x) / cos x
The correct answer is C.
Hope this helps
