Find the minimum value of the function, f(x)= x^2 + 5x + 2, where x belongs to the set of Real numbers

State the conditions under which a binomial distribution can be approximated as a normal distribution, and state how the parameters needed would be calculated.

If the function f is defined as f= 1-2x^3 find the inverse f^-1

The point P (4, –1) lies on the curve C with equation y = f( x ), x > 0, and f '(x) =x/2 - 6/√x + 3. Find the equation of the tangent to C at the point P , giving your answer in the form y = mx + c. Find f(x)
