Math Problem Statement
Solution
The image contains the following problem based on transformations of the function :
Problem: Starting with the graph of , write the equation of the graph that results from:
(a) Writing 3 units upwards:
(b) Shifting 2 units to the left:
(c) Reflecting about the x-axis:
Solutions:
-
(a) Writing 3 units upwards:
To shift a function upwards by units, you add to the function:
-
(b) Shifting 2 units to the left:
To shift a function left by units, you replace with :
-
(c) Reflecting about the x-axis:
To reflect a function about the x-axis, you multiply the function by :
Would you like further details on transformations or have any questions about these steps? Here are 5 related questions:
- How would you shift by 4 units to the right?
- What would the equation be if was reflected over the y-axis instead of the x-axis?
- How do you vertically stretch by a factor of 2?
- How can we reflect over both the x-axis and the y-axis?
- What happens to the graph when you shift it both horizontally and vertically?
Tip: When shifting graphs, always check whether the shift is horizontal or vertical, as each type has a different effect on the equation.
