Step-by-step explanation
We are asked to describe the translation of the functions with respect to f(x) =x
To translate the function up and down, you simply add or subtract numbers from the whole function. If you add a positive number (or subtract a negative number), you translate the function up. If you subtract a positive number (or add a negative number), you translate the function down.
In function notation, to shift a function left, add inside the function's argument: f(x + b) shifts f(x) b units to the left. Shifting to the right works the same way, f(x - b) shifts f(x) b units to the right.
To do so, we will have to plot the graph of each function and compare it with f(x) represented by the red lines below
Part A
Thus, we will have
For part B
when
The translation here is
Part C
For the function
The graph is
Thus, we have the translation as A horizontal shift to the left by 2 units
Part D
The given function is
The transformed graph is
The translation is a shift to the right by 7.5 units
