Answer:

3 x (3 x - 5) (3 x + 5)

Step-by-step explanation:

Factor the following:

27 x^3 - 75 x

Factor 3 x out of 27 x^3 - 75 x:

3 x (9 x^2 - 25)

9 x^2 - 25 = (3 x)^2 - 5^2:

3 x (3 x)^2 - 5^2

Factor the difference of two squares. (3 x)^2 - 5^2 = (3 x - 5) (3 x + 5):

Answer: 3 x (3 x - 5) (3 x + 5)

If the line in the graph is shifted up two units which is the equation of the new line
anastassius [24]

Answer:

f(x) + 2.

Step-by-step explanation:

Example:

If we have say f(x) = x + 1 then 2 units will be added to f(x) when it is moved up 2 units.

So the equation of this line will be f(x) + 2 which in this example is

x + 1+ 2.

The new function is  x + 3.
