Graph OF Quadratic Expression

Find the maximum and minimum values of the expression: a cos theta+b sin theta

(1) The minimum value of the quadratic expression x^(2)+bx+c is (2) if maximum value at x=a then a=

If a and b are the maximum and minimum values of the quadratic expressions 1-2x-5x^(2) and x^(2)-2x+5 respectively then the set of the all values of x for which the expression 5ax^(2)+bx+7 is positive

If the minimum value of the quadratic expression y =ax ^(2)+bx +c is negative attained at negative vlaue of x, then :
