Only 25 and 28 are functions.
A function must have only one y value per x value. For 26, the y value of 0 and multiple others have two different y values. For 27, all x values less than 0 have multiple y values.
If the apple is on the ground, then the height y is 0. To find t, just plug in 0 for y:




So the answer is 2.74 seconds.
