Answer:
as written: 7x^2
perhaps intended: 7x^4
Step-by-step explanation:
As written, the Order of Operations specifies that the only denominator factor is 3, so the expression is interpreted as ...
___

Answer:
B. f(x) = x^2 -2
Step-by-step explanation:
The graph of f(x) is the graph of g(x) moved down 2 units, so is ...
f(x) = g(x) -2
f(x) = x^2 -2
_____
Adding a constant to the value of a function moves the graph vertically by the value of the added constant.
Answer:
$6 for a 1-minute call
Step-by-step explanation:
For duration "d" the costs of the plans are identical when ...
5 +1d = 1 +5d
4 = 4d . . . . . . . . add -1-1d to both sides
1 = d . . . . . . . . . divide by 4. Duration in minutes.
Then the cost for this 1-minute call is ...
5 + 1·1 = 6 . . . . dollars
Each plan will charge $6 for a 1-minute call.
