The minimum value or least value of the function is -16 at x = 4 after plotting the graph.
What is a quadratic equation?
Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
We have:
(8,0) is on y=bx+x²
Plug x = 8 and y = 0
0 = 8b + 64
b = -8
y = -8x + x²
Thus, the minimum value or least value of the function is -16 at x = 4 after plotting the graph.
