Rhianna graphed a square root function. What is the equation of the function she graphed? (1 point) Responses y=12x−4−−−−−√ y equals Start Fraction 1 over 2 End Fraction Start Root x minus 4 End Root y=12x+4−−−−−√ y equals Start Fraction 1 over 2 End Fraction Start Root x plus 4 End Root y=2x+4−−−−−√ y equals 2 Start Root x plus 4 End Root y=2x−4−−−−−√
The correct equation for the square root function that Rihanna graphed is:
y = 2√(x - 4)
