Paragraph: Graph of f( x )= ax ^2+ bx + c is shown adjacently, for which ( AB )=2, ( AC )=3 and b ^2-4 ac =-4 On the basis of above informations, answer the following questions : Question: Range of g(x)= (a+ 1 2 ) x^2+(b+2) x- (c- 1 2 ) when x [-4,0] is -

Quantrex Academy · Accepted Answer

Correct answer: C. [- 49 4 ,-6 ]

aligned & g(x)=x^2+5 x-6=(x+6)(x-1) & g(-4)=-10 & g(0)=-6 aligned g(x)_ =- 49 4 at x=- 5 2 Range of g(x) is [- 49 4 ,-6 ]
