Question

which of the following describes the graph of y= sqrt -4x-36 compared to the parent square root function?

Answer 1

Answer: The answer is D

Explanation:

i just did it

Answer 2

Please see attached graph for answer.

Explanation:

We can easily solve this question by plotting the graphs of both functions in a graphing calculator.

We have

y = √(-4x-36)

y = √(-4(x+9))

g = √(x)

We can see that the function y corresponds to a mirrored version of function g. Each x is scaled by a factor of -4, and shifted to the left in 9 units
