Quadratic Functions Unit 3 26 Correctly Answered Questions Latest Update

factored form {Ans: A quadratic function is is factored form when it is written in the form f(x)= a(x-r1)(x-r2) where a does not equal o. The function h(x)=2x^2+14x+24 is 2(x+3)(x+4) in factored form.}Zero Product Property {Ans: The Zero Product property states that if the product of two or more factors equals to zero, then at least one factor must equal zero. Ex. If (x-2)(x+3)=0, then x-2=0 OR x+3=0.}Quadratic Formula {Ans: A formula that can be used to find the solution to any quadratic equation.}Difference of Two Squares {Ans: a squared (multiplied by itself) number subtracted from another squared number. It refers to the identity in elementary algebra.}factor an expression {Ans: to factor an expression means to use the Distributive Property in reverse to rewrite the expression as a product of factors. Ex. 3x +18 can be factored as 3(x+6)}vertical motion model {Ans: A vertical motion model is a quadratic equation that models the height of an object at a given time. The equation is of the form g(t)=-16t^2 + v0t +h0 where g(t) represents the height of the object in feet, t represents the time in seconds that the object has been moving, v0
