Which of the quadratic functions shown graphed below would have a negative discriminant? (1) (3) (2) (4)

2 A golf ball is struck by a 60-degree golf club at an initial velocity of 90 feet per second. The height of the golf ball in feet is given by the quadratic function h(x) = 16x 77.9 + -x, where x is the 45 (45)² horizontal distance of the golf ball from the point of impact. What is the horizontal distance of the golf ball from the point of impact when the ball is at its maximum height? What is the maximum height obtained by the golf ball? The horizontal distance of the golf ball from the point of impact when the ball is at its maximum height is (Round to two decimal places as needed.) feet.

The following quadratic function is expressed in both its expanded and factored form below: f(x) = 2x² – 7x + 3 = (2x – 1)(x – 3) Choose the correct match for the coordinates of the x and y intercepts of f(x) . y intercept(s) of f(x) x intercept(s) of f(x)

Identify the equation of the quadratic function with a vertex of (0, − 1), that passes through the point (3, 4 109 14⁹) and opens downward. ƒ (x) = 3x² + 1⁄2 ƒ (x) = −3x² + 1/ 4 ƒ (x) = −3x² ƒf (x) = 3x² 1 H|2 1 4
