Question

what is the minimum value of the function f(x)=100x^2-1700x

Answer 1

well notice that you have a parabola equation, the leading term coefficient is positive, that is +100
so that means that the parabola is going UPWARDS like

so the lowest point, that is, the MINIMUM VALUE, will be found at its vertex

for a parabola equation of type \(\bf \large ax^2+bx+c\) you can find the vertex at the coordiinates of \(\bf \left(-\cfrac{b}{2a}\quad ,\quad c-\cfrac{b^2}{4a}\right)\)
