Question

For the parent function y equals the square root of x, what effect does a value of b = -2 have on the graph?
A. Horizontal compression by a factor of one half and a reflection across the y-axis
B. Horizontal compression by a factor of one half and a reflection across the x-axis
C. Horizontal compression by a factor of negative one half and a reflection across the y-axis
D. Horizontal compression by a factor of negative one half and a reflection across the x-axis

Answer 1

@ceecee_millions is it C?

Answer 2

Answer 3

so the equation is

\[y = \sqrt{x}\]

where does the b go...?

1. \[y = \sqrt{x} + b\]

or

2.

\[y = \sqrt{x + b}\]

Answer 4

but a really good method for this is to use some graphing software and look at things yourself.
