Question

Which of the following functions are vertical translations of f(x)=√x?

Select all that apply.
A. K(x)=√√√-5+x
B. n(x) = -7+ √x
C. g(x)=√x -4
D. h(x)=3+√x
E. m(x)=√5x

Answer 1

The function f(x) = √x is the square root function.

A vertical translation of a function is a transformation that shifts the graph of the function up or down without changing its shape.

Option (A) is a vertical translation of f(x) because it shifts the graph of f(x) to the right by 5 and then applies three square root operations. However, it is not a vertical translation that shifts the graph up or down.

Option (B) is a vertical translation of f(x) because it shifts the graph of f(x) down by 7 units.

Option (C) is a vertical translation of f(x) because it shifts the graph of f(x) down by 4 units.

Option (D) is a vertical translation of f(x) because it shifts the graph of f(x) up by 3 units.

Option (E) is not a vertical translation of f(x) because it involves multiplying the input of f(x) by a constant factor of 5.

Therefore, the options that are vertical translations of f(x) are (B), (C), and (D).
