Question

Relative Minimum
Is the relative minimum value the y value?

Answer 1

I am given f(x) = x^3-8x^2+5-5
I know the min is located at (5, -55)
the multiple choice list 5 and -55. Do I pick -55 because it is a low point?

Answer 2

relative minimum value is -55,

Answer 3

it occurs at x = 5

Answer 4

Yeah to say 5 is your minimum is obviously wrong because 4 is smaller than 5. You have no restriction on your domain so you could go all the way to negative infinity basically.

Answer 5

f(5) = -55
^^^^

-55 is the function value; 5 is the input to function. feel it :)

Answer 7

felt it haha ;)

Answer 8

@precal more complicatedly :

(5, -55) is the point at which minimum occurs,
this point can be represented as : (x, f(x)) = (5, f(5))

that may make it convincing to see that the function takes in 5, and spits out the value -55
