" 26."(sqrt(2x^(2)+7x-4))/(x+4)<(1)/(2)

If y= 3sqrt ((2x^(2) -7x -4) ^(5) ) ,then (dy)/(dx) =

7sqrt(2)x^(2)-10x-4sqrt(2)

State the coefficient of x^(2) in each of the following polynomials : sqrt(2)x^(2) + 7x - 4sqrt(2)

Write the following polynomials is standard form. (i) x-9+sqrt 7x^(3) +6x^(2) (ii) sqrt 2x^(2) -(7)/(2) x^(4) +x -5x ^(3) (iii) 7x^(3) - ( 6)/(5) x^(3) +4x -1 (iv) y^(2) +sqrt5y ^(3) -11 -(7)/(3) y+9y^(4)

lim_ (x rarr-oo) (sqrt (4x ^ (2) -7x) + 2x)

lim_(x rarr sqrt(2))(x^(2)-3sqrt(2)x+4)/(x^(3)+7x-9sqrt(2))

Evaluate {:(" Lt"),(xrarr2):}(2x^(2)-7x-4)/((2x-1)(sqrt(x)-2))
