Number 16 and 17 i dont know how to solve it

16) B

17) B

Step-by-step explanation:

16)

Domain is the largestest and smallest x values your graph can reach

Since your graph ends at the points (1,4) and (6,4) those x values are the domain; 1≤x≤6

Range is the largest and smallest y values your graph can reach. The highest part of your graph is (2,1) and (4,7) which means those y values are the range; 1≤x≤7

17)

(f°g)(x) just means that for the x values in the f(x) equation you will insert the g(x) equation;

(f°g)(x)=(1/x-2) / (1/x-2)+1

To find the domain of a fraction the numerator or denominator must not equal 0 because then the whole fraction equals 0 and you can't take 0 parts of something so it doesn't exist.

So for g(x) the fraction is; 1/x-2

x cannot equal +2 or the fraction will be dividing by 0 and that can't happen

For f(x) the fraction is; x/x+1

x cannot equal -1 or the fraction will be dividing by 0 and that can't happen

I hope this helps!

I don't really know what the degrees symbol means in algebra, but I can help with 16, sorry about that

16 is B

Step-by-step explanation:

Look at the graph. Looking at the x-axis, it only ranges from 1-6, and this includes x=1 and x=6 because the dots are filled in (has to do with 'including and greater than' stuff). Same with the y-axis; it only goes from y=1 to y=7.

answer: 5100 just subtract
