Question
If you shift the linear parent function, f(x) = x
, to the left 5 units, what is the equation of the new function?
A. g(x) = 5
B. g(x) = 5x
C. g(x) = x
D. g(x) = x + 5
Solution
To shift the linear parent function to the left by 5 units, you need to adjust the input by adding 5 to it. This is because shifting to the left involves increasing the value of by the shift amount.
Here are the steps:
- Start with the original function: .
- To shift the function to the left by 5 units, replace with .
So, the new function will be:
Since , we substitute into the function:
Therefore, the equation of the new function is:
