Rhianna graphed a square root function. What is the equation of the function she graphed? (1 point) Responses

y=2x+4−−−−−√ y
y=12x+4−−−−−√
y=12x−4−−−−−√
y=2x−4−−−−−√

Without seeing the graph, we cannot determine the exact equation of the square root function. However, based on the given options, the equation that might represent the square root function graphed by Rhianna is:

y = 2x - 4√
