Let f(x)=|x| and g(x)=x+2. What are the domain and range of (f o g)(x)?
A. Domain: x>=-2
Range: all real
B. Domain: x>=0
Range: all real
C. Domain: all real
Range: y>=0
D. Domain: all real
Range: all real

the answer is c. hope this !

step-by-step explanation:

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

im not sure

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
