find and symplify the following. Integrate ( 2x^5 - 1/(4x^3)- 5 )dx

first the second term can be split up to make integrating it easierits easier if the x 3 component is separatedthis eventually simplifies the second term to (-1/4) * x -3 so now the question is integrate (2x...

Consider the functions f(x) = −x^3 + 2x^2 + 3x and g(x) = −x^3 + 3x^2 − x + 3. (a) Find df/dx (x) and hence show that f(x) has turning points at when x = 2 /3 ± √ 13/ 3 . [5] (b) Find the points where f(x) and g(x) intersect. [4]

a) First differentiate f(x) using standard polynomial derivative rules which gives, df/dx=-3x^2+4x+3. The derivative function gives the gradient of f for any value of x. Turning points occur when the gradien...
