Find y please and thanks

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

Solve each quadratic equation by factoring and using the zero product property. n^2 - 49 = 0

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
