Clearing r we have:
Answer:
a reasonable domain for f (r) is:
7 <r <14
It does not represent a polynomial
Answer:
B
Step-by-step explanation:
Pick any point on both triangles and compare the points to see how they changed.
C to F went from (0,4) to (0,2) went down by 1/2
and it's a dilation of the bigger one of 1/2 so it's B
Answer:
a) g(x) = (x - 3)^3
Step-by-step explanation:
because the function has shifted horizontally to the right 3 units, the 3 has to be within the parentheses. additionally, because it's moved to the right 3 units, the term inside the parentheses is -3. you would think it'd be +3, but it's actually the other way around. i hope this helps! :)
