The graph of the quadratic function shown on the left is y = –0.7(x + 3)(x – 4). The roots, or zeros, of the function are . Determine the solutions to the related equation 0 = –0.7(x + 3)(x – 4). The solutions to the equation are x = .

The focus of parabola is (-4, -5), and its directrix is y= -1. fill in the missing terms and signs in parabolas equation in standard form

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2
