Please help, Describe the transformation of the graph of the parent function y = √x for the function y = √x + 7 + 5.

Setler79 [48]

Answer:

C. Up.

Step-by-step explanation:

We have been given that the parent function $y=\sqrt{x}$ is transformed to the function $y=\sqrt{x+7}+5$ . We are asked to describe the given transformation.

Let us recall the transformation rules.

$f(x+a)=\text{Graph shifted to left by a units}$ ,

$f(x-a)=\text{Graph shifted to right by a units}$ ,

$f(x)+a=\text{Graph shifted upwards by a units}$ ,

$f(x)-a=\text{Graph shifted downwards by a units}$ .

Upon comparing our transformed function with the parent function, we can see that the graph is shifted to left by 7 units and upwards by 5 units.

Therefore the correct choice is option C.
