f(x)=(x-a)^(2)+(x-b)^(2)+(x-c)^(2)" has minimum value at "x=......

Let f(x)=(x-a)^(2)+(x-b)^(2)+(x-c)^(2) Then,f(x) has a minimum at x=(a+b+c)/(3)(b)(1)/(2) (c) (1)/(8) (d) none of these

The function f(x)=(x-1)^2+(x-2)^2+(x-3)^2+……+(x-9)^2 has minimum value at x=

Let f(x)=(x-a)^(2)+(x-b)^(2)+(x-c)^(2) Then,f(x) has a minimum at x=(a+b+c)/(3) (b) 3sqrt(abc)(c)(3)/((1)/(a)+(1)/(b)+(1)/(c))( d) none of these

f(x)=2x^(3)-18 x^(2)+30x+36 has minimum value at x =

Let f(x)=(x-a)^2+(x-b)^2+(x-c)^2dot Then, f(x) has a minimum at x= (a+b+c)/3 (b) 1/2 (c) 1/8 (d) none of these

Let f(x)=(x-a)^2+(x-b)^2+(x-c)^2 . Then, f(x) has a minimum at x= (a+b+c)/3 (b) 3sqrt(a b c) (c) 3/(1/a+1/b+1/c) (d) none of these

f(x)=2x^(3)-18x^(2)+30x+36 has minimum value at x = ….

Show that , f(x)=x^(2)+(250)/(x) has a minimum value at x=5.
