Parabolas always open up.

The first differences for the function y = 3x + 5 are all the same (constant).

The vertex lies halfway between the x-intercepts.

The expression -16×2 – 80x written in factored form is:

Which of the following is true about Locke’s idea of Social Contract ?

The graph below models the path of a basketball after it was thrown from a player’s hands to the basketball hoop, through the net, and down to the floor. The h values represent the height of the ball in feet above the floor and the d values represent the horizontal distance in feet from the player’s hands.   What was the height of the ball, when it was first released from the player’s hands?  Accuracy to the nearest tenth.  Don’t forget your units! The height of the ball at initial release is 

Algebraically determine the zero(s) of the quadratic relation y = x2 – 25.  Please list as coordinates. The coordinate(s) of the zero(s) is / are:

Identify which statement is true of the graph and equation for this quadratic:

The x-intercepts (zeroes) of y = x2 – 5x – 6 are (-6, 0) and (1, 0).
