Describe how to translate the graph of y=square root of x to obtain the graph of y=x-9

general rule to be used here for translation is f(x) - d, vertical translation down d units.

Using this rule here f(x)=√x to f(x) = √x -9

we are moving 9 units down

so answer is shifts 9 units down

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

answer: 5
