Question

Due in 6 hours, 55 minutes. Due Fri 06/01/2018 12:59 am Properties of Quadratic Functions According to the Mini-Lesson, which of the following are TRUE about Quadratic Functions? Check all that apply OThe Vertical Intercept is (0, a) a determines which direction the parabola opens (up or down) There are 4 distinct terms, each with its own coefficient The constant term is c A Quadratic Function is of the form f(x) az + ba + o Applications of Quadratic Functions The function h(t)162 +80t +130, where t is time in seconds and h(t) is the height of the arrow in feet, models the height of an arrow shot into the sky as a function of time. Given that function, which of the following are true? Check all that apply. The Practical Domain of the function is from 0 to the input value of the vertex The input value of the Vertex is the time it takes for the arrow to reach its highest point OThe output value of the Vertical Intercept is the height of the arrow at timet0 OThe input value of the horizontal intercept is the distance the arrow has traveled before it hits the ground The Practical Range of the function is from 0 to the output value of the vertex PhotoGrid

Explanation / Answer

1) The statements which are true about quadratic functions are as follows :

(i) 'a' determines which direction the parabola opens (up or down)

(ii) The constant term is c

(iii) A Quadratic function is of the form f(x) = ax2+bx+c.
