Lisa solved 3x2 + 1 = 28 as shown. 3x2 + 1 = 28 3x2 = 27 x2 = 9 she concluded that the solutions to this quadratic equation are x = -9 or x = 9. what are the correct solutions to this quadratic and how did you arrive at your answer?

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

Answer: c. x y2 04 66 16
