Answer:
17
Step-by-step explanation:
Answer:
18 since 12 x 2 = 24 so 9 x 2 = 18
Step-by-step explanation:
Answer:
R-{13}
Step-by-step explanation:
We are given that


We have to find the domain of fog(x).



Domain of f(x)=R
Because it is linear function.
Domain of g(x)=R-{13}
Because the g(x) is not defined at x=13
fog(x) is not defined at x=13
Therefore, domain of fog(x)=R-{13}
Estimate 189 to the nearest tenth which would be 190. And then do the same for 643 which would be 640. 640-190= 450
