Graph of `f(x)=ax^2+bx+c` is shown adjacently, for which `iota (AB)-2,iota (AC)=3` and `b^2-4ac=-4`. On the basis of above informations , answer the following questions:The value of `a + b +c` is equal to

Let a,b,c,d be the foru cosecutive coefficients int eh binomial expansion (1+x)^n On the basis of above information answer the following question: The value of n is (A) (2ac-b(a+c))/(b^2-ac) (B) (2ac+b(a+c))/(b^2-ac) (C) (2ac)/(a+c)-b (D) (b^2-ac)/(2ac+b(a+c)

If graph of y=ax^(2)+bx+c is as shown,then which of the following is correct? (where D equals b^(2)-4ac)

if a gt 0 and b^2 - 4ac =0 , then the curve y= ax^2 +bx +c

The graph of the polynomial f(x)=ax^(2)+bx+c is as shown in Fig.2.20. Write the value of b^(2)-4ac and the number of real zeros of f(x).( FIGURE )

If a>0 and b^(2)-4ac<0, then the graph of y=ax^(2)+bx+c

If a>0 and b^(2)-4ac=0, then the graph of y=ax^(2)+bx+c touches x -axis and lies above x -axis.

Let f(x)=ax^(2)+bx + c , where a in R^(+) and b^(2)-4ac lt 0 . Area bounded by y = f(x) , x-axis and the lines x = 0, x = 1, is equal to :
