A person dives into a pool from its edge to swim to the other side. The data can be modeled by a quadratic function. Which function best models the data?

d(x) = 0.05x² + 0.74x

d(x) = 0.05x² + 0.74x + 9.17

d(x) = 0.26x² - 3.11x

d(x) = 0.26x² - 3.11x + 1

The solutions to p(x) = 0 are x = -7 and x = 7. Which quadratic function could represent p?

p(x) = x² - 49

p(x) = x² + 49

p(x) = x² - 14

p(x) = x² + 14

Two points are plotted on the grid. Which equation in slope-intercept form best represents the line that passes through these two points?

y = -2/3x - 11/3

y = -11/3x - 2/3

y = -2/3x - 10/3

A construction manager is monitoring the progress of the build of a new house. The scatterplot and table show the number of months since the start of the build and the percentage of the house still left to build. A linear function can be used to model this relationship. Which function best models the data?

y = -13.5x + 97.8

y = -13.5x + 7.3

y = 97.8x - 13.5

y = 7.3x - 97.8

Given f(x) = x² - 36, which statement is true?

The only zero, 6, can be found when (x - 6)(x - 6)
