Question

Which of the following describes the graph of y=sq -4x-36 compared to the parent square root function

Answer 1

D: Stretched by a factor of 2, reflected over the y-axis, and translated 9 units left

Explanation:

I actually just did this and used the answer above and got it wrong, so the answer I put down is the correct answer according to edg... Good Luck!!!

Answer 2

Explanation:

First, let's simplify the equation:

y = √(-4x - 36)

y = √(4(-x - 9))

y = 2√(-x - 9)

The 2 coefficient in front means the function is stretched by a factor of 2.

The - sign in front of the x means the function is reflected over the y axis.

The -9 constant means the function is shifted 9 units to the right.

The third one is the correct answer.
