Answer:
A Irrational
Step-by-step explanation:
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
Well, i have the answer to your question:
dealership A : 500 cash back , 5% tax
Becky : 15,000 + 0.05(15000) - 500 = 15,000 + 750 - 500 = 15,250
Michele : 20,000 + 0.05(20,000) - 500 = 20,000 + 1000 - 500 = 20500
dealership B : 1000 cash back, 8% tax
Becky : 15,000 + 0.08(15,000) - 1000 = 15000 + 1200 - 1000 = 15,200
Michele : 20,000 + 0.08(20,000) - 1000 = 20,000 + 1600 - 1000 = 20600
1. Becky will get the better deal at dealership B.....she saves 50 bucks
2. Michele will get the better deal at dealership A...she saves 100 bucks
