we are given
Firstly, we will find domain of c(x) , d(x) and then (cd)(x)
and then we can find common domain
Domain of c(x):
we know that domain is all possible values of x for which domain is defined
we know that any function is undefined when denominator =0
x-2=0
x=2
so, domain of c(x) is all values of x except at x=2
Domain of d(x):
we know that domain is all possible values of x for which domain is defined
we know that any function is undefined when denominator =0
we don't have denominator here
so, domain of d(x) is all real values of x
Domain of (cd)(x):
we know that domain is all possible values of x for which domain is defined
we know that any function is undefined when denominator =0
x-2=0
x=2
so, domain of c(x) is all values of x except at x=2
so, common domain is all real values of x except at x=2
so, option-B........Answer

Answer:
Step-by-step explanation:
When x represents the number, "the sum of 3 and a number" is (x+3). Twice that sum is 2(x+3). "Is 30" means this expression is equal to 30:
2(x +3) = 30 . . . . an equation for the given conditions
__
We can solve this equation by dividing by 2:
x + 3 = 15
x = 12 . . . . . . subtract 3
The number is 12.

<h3>Use formula of acceleration = final velocity - initial velocity / time taken or, v - u / t</h3>
I think this helpful for you.
Thank you ☺️☺️
A
y = m x + b
y = -1 x + -6
y = -x - 6
