Answer:
The degree of (f × g × h)(x) is 7.
i.e option a ) 7
Step-by-step explanation:
Given:
To Find:
Degree of (f × g × h)(x) = ?
Solution:
For multiplication of given function we require
Law of indices:
Distributive Property:
(A + B)(C + D) = A (C + D) + B(C +D)
= AC + AD + BC +BD
Now,
Degree is highest power raised to the variable.
Therefore here highest power raised to the variable is 7
Therefore degree of (f × g × h)(x) is 7.
