## anonymous one year ago 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

@ceecee_millions is it C?

so the equation is $y = \sqrt{x}$ where does the b go...? 1. $y = \sqrt{x} + b$ or 2. $y = \sqrt{x + b}$

but a really good method for this is to use some graphing software and look at things yourself. I'd recommend https://www.desmos.com/calculator
