Math Problem Statement
Answer each of the following questions about the graph for y=7|x+3|+6
-
Does the graph open up or down? Select an answer Up Down
-
Give the vertex as an ordered pair.
-
Is this point the maximum or minimum of the graph? Select an answer Maximum Minimum
-
Is the graph wider, narrower, or the same width as the parent function y=|x|? Select an answer Wider Narrower Same Width
-
From the parent fucntion y=|x| this graph has been shift horizontally ? 6 3 unit(s) to the Select an answer Left Up Right Down
-
From the parent function y=|x| this graph has been shifted vertically ? 6 3 unit(s) Select an answer Down Left Right Up .
Solution
Let's break down each question using the given equation , which represents a transformation of the parent function .
-
Does the graph open up or down?
- The coefficient of is positive (7), so the graph opens Up.
-
Give the vertex as an ordered pair.
- The vertex form of the absolute value function is , where is the vertex.
- In this case, the vertex is .
-
Is this point the maximum or minimum of the graph?
- Since the graph opens upwards, the vertex represents the lowest point (minimum).
- Therefore, this point is the Minimum.
-
Is the graph wider, narrower, or the same width as the parent function ?
- The coefficient of is 7, which stretches the graph vertically, making it Narrower than the parent function .
-
From the parent function , this graph has been shifted horizontally:
- The graph shifts horizontally by 3 units to the Left (since means a shift left by 3 units).
-
From the parent function , this graph has been shifted vertically:
- The graph shifts vertically by 6 units Up (since the constant is +6).
Summary:
- Up
- (-3, 6)
- Minimum
- Narrower
- 3 units to the Left
- 6 units Up
Would you like more details on any of these transformations or concepts?
Here are 5 questions that extend this topic:
- What happens if the coefficient of the absolute value function is negative?
- How does changing the constant outside the absolute value affect the graph's vertical position?
- How would the graph shift if the equation was ?
- What is the effect of changing the coefficient inside the absolute value (e.g., )?
- How does the steepness of the graph change with different coefficients of the absolute value term?
Tip: The graph of an absolute value function is symmetric with respect to its vertex, meaning the left and right branches mirror each other.
