2. What will be the nature of the graph of the following polynomials(i) ax? + bx+c when a > 0(ii) a x? + bx+c when a < 0 About the author Audrey
Answer: Let ax 2 +bx+c=y ⇒x 2 + a b x+ a c = a y ⇒x 2 +2 2a b x+( 2a b ) 2 = a y +( 2a b ) 2 ⇒(x+ 2a b ) 2 = a y +( 2a b ) 2 ⇒X 2 =Y Step-by-step explanation: So it s an equation of a parabola. The graph will be that of a parabola Reply
Answer:Here is Ur answer Step-by-step explanation: 1) when a value of a is greater than 0 ,then the graph representation (curves/parabolas)will be open upward.. 2) when a value of a is less than 0 ,then graph representation will have open downwards ..Hope this answer is useful in ur studies..Happy Learning..
