Answer:
A
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Here f(x) is shifted 3 units left , then
f(x) → f(x + 3)
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here f(x) is shifted 4 units down , then
f(x) → f(x) - 4
Thus
f(x) = → f(x) =
- 4

Answer:
C) domain: all real numbers greater than or equal to 0
range: all real numbers greater than or equal to 13,000
Step-by-step explanation:
We have, the function for the cost of laying cable is given by,
, where x is the length of the cable (in feet).
As, 'x' represents the length of the cable.
We have that, the value of x cannot be negative.
So, x ≥ 0.
Since, the domain of is the set of points where
and we have that x ≥ 0.
Thus, the domain is 'Set of all real numbers greater than or equal to 0'.
Now, we substitute x= 0 in .
i.e.
i.e.
i.e.
i.e. c(0) = 13000.
So, we get that the vertex point of the function is (0,13000).
Thus, the range is 'All real numbers greater than or equal to 13,000'.
