If the question had asked what is the value of x if the Function attained a Maximum value in the XY Plane? Please, advise.

Sharvil93 zondiceThe function y=px2−4x+q in the x-y plane attains a minimum value. What is the value of x?

1) p=2

2) q=5

Please note that y=px2−4x+q represents Parabola.

If p is positive then function will attain minima at some value of X (i.e. X= -b/2a) (Parabola open towards +ve Y- axis)

If p is negative then funcation will attain maxima at some value of X (i.e. X = -b/2a) ((Parabola open towards -ve Y- axis)

Hope this helps!!
