Question

3. Which statement describes the translation of y= -5(x2 + 2) - 3 from standard position?

Moved up and to the right.
Moved up and to the left.
Moved down and to the left.
Moved down and to the right.

4. What is the range of the graph of y = 5(x - 2)2 + 7?

y greater than or equal to 7
y less than or greater to 7
y greater than or equal to 2
y less than or greater to 2

13. What value is added to both sides of the equation x2 - 4x = -2 in order to solve by completing the square?

4
2
-2
-4

Answer 1

@satellite73 can you please help me with these three problems?

Answer 2

\[ y= -5(x^2 + 2) - 3 \]

Answer 3

the \(-3\) at the end moves it down 3 units
the \(+2\) insides moves it to the LEFT 2 units

Answer 4

What is the range of the graph of \(y = 5(x - 2)^2 + 7\)?
\((x-2)^2\) is always greater than or equal to zero, because it is a square
therefore so is \(5(x-2)^2\)
that makes \(5(x-2)^2+7\) always greater than or equal to \(7\)

Answer 5

@satellite73 Thank you so much! and the last one?

Answer 6

would it be 4?
