Answer:
Option (2)
Step-by-step explanation:
Given functions are,
c(x) = 
d(x) = x + 3
Equation of the composite function will be,
(cd)(x) = c(x) × d(x)
= 
= 
This function is defined only when denominator is not equal to zero.
(x - 2) ≠ 2
Therefore, for real numbers except x = 2 will be the domain of the composite function.
Option (2) will be the answer.
The value of c is 81/64 for the expression a perfect square trinomial.
<h3>
What is an Expression?</h3>
An expression can be defined as a mathematical statement that consists of variables, constants and mathematical operators simultaneously.
It is given that an expression
x² +9/4x +c is a perfect square polynomial
c =?
(a+b)² = a² +2ab+b²
2ab = 9/4
b = 9/8
c = b² = 81/64
Therefore the value of c is 81/64 for the expression a perfect square trinomial.

<h2>
The next terms are 16, 10, 4</h2>
Step-by-step explanation:
The given series is 46, 40, 34, 28, 22,... , ...., .....
The difference between each
46 -40 = 6
40 - 34 = 6
34 -28 = 6
28 - 22 = 6
22- x = 6 => 16
16 - x = 6 => 10
10 - x = 6 => 4
Anything to the 0 power is 1
and 1 to the any power is 1
so x can be any number
