Which statement correctly describes the relationship between the graph of f (x) = 2x and the graph of g (x) = f (x) − 4? a. the graph of g (x) is the graph of f (x) translated 4 units up. b. the graph of g (x) is the graph of f (x) translated 4 units right. c. the graph of g (x) is the graph of f (x) translated 4 units left. d. the graph of g (x) is the graph of f (x) translated 4 units down.

D. The graph of g (x) is the graph of f (x) translated 4 units down.

Explanation:

To show a translation left or right, we add or subtract a value to x before the function is applied.  That is not what has happened to this function, therefore this was not a horizontal translation.

To show a translation up or down, we add or subtract a value at the end of a function.  The function g(x) = f(x) - 4 subtracts 4 from the end of the function f(x); this means that the function has been translated down 4 units.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
