Find the absolute maximum and absolute minimum values, if any, of the function. (If an answer does not exist, enter DNE.)f(x) =
lyudmila [28]

Answer:

The absolute minimum value is "-\frac{21}{4}" and the absolute maximum value is "15".

Step-by-step explanation:

Given:

f(x)=x^2-x-5

on,

[0,5]

By differentiating it, we get

⇒ f'(x)=2x-1

Set f'(x)=0

then,

⇒ 2x-1=0

          2x=1

            x=\frac{1}{2} (Critical point)

When x=0,

⇒ f(x)=-5

When x=\frac{1}{2},

⇒ f(x)=-\frac{21}{4} (Absolute minimum)

When x=5

⇒ f(x)=15 (Absolute maximum)

The midpoint of AB is M(1, 3). If the coordinates of A are(4,1), what are the coordinates of B?
Oxana [17]

Answer:

B(-2,5)

Step-by-step explanation:

\frac{x + 4}{2}  = 1 \\ 2 \times  \frac{x + 4}{2}  = 1 \times 2 \\ x + 4 = 2 \\ x = 2 - 4 \\ x =  - 2 \\  \frac{y + 1}{2}  = 3 \\ 2 \times  \frac{y + 1}{2}  = 3 \times 2 \\ y + 1 = 6 \\ y = 6  -  1 \\ y = 5

Hope that this is helpful.

Have a nice day.
