I tried this:
Explanation:
This is a Quadratic Function that is represented by a Parabola. Due to the positive coefficient of
To find the coordinates of the minimum you can derive the function:
and set this equal to zero:
solve it:
substitute this into your original function to get the
Graphically:
graph{(3/4)x^2-5x-2 [-10, 10, -5, 5]}
Remember that the derivative is a representation of the Inclination of your curve; so when the derivative is zero it means your curve is neither going up nor down...i.e. it is a max or min!!!
