Find the domain of the function What is the domain off O A 7

Find the domain of the function. What is the domain off? O A. [-7,00) O B. [13, oo) O c. 10,00) O D. 00.00

Solution

given f(x)=(x-13) +(x+7)

x-13>=0

=>x >=13

[13,)

x+7>=0

=>x>=-7

[-7,)

domain is [-7,)n[13,)....................................(n indicates intersection)

domain is [13,)
