What is the value of the expression f(–3)? -15 3 -3 15

Answer:

Option A, -15

Step-by-step explanation:

<u>Step 1:  Look at the function that needs to be outputted when x = -3</u>

Since x = -3, that means it falls into the first category of x ≤ -3

<u>Step 2:  Carry out the instructions</u>

The function for the first category is -x^{2} + 2x

f(-3) =-(-3)^{2}+2(-3)

f(-3) = -(9) - 6

f(-3) = -15

Answer:  Option A, -15

Find the max and min values of f(x,y,z)=x+y-z on the sphere x^2+y^2+z^2=81
Anton [14]
Using Lagrange multipliers, we have the Lagrangian

L(x,y,z,\lambda)=x+y-z+\lambda(x^2+y^2+z^2-81)

with partial derivatives (set equal to 0)

L_x=1+2\lambda x=0\implies x=-\dfrac1{2\lambda}
L_y=1+2\lambda y=0\implies y=-\dfrac1{2\lambda}
L_z=-1+2\lambda z=0\implies z=\dfrac1{2\lambda}
L_\lambda=x^2+y^2+z^2-81=0\implies x^2+y^2+z^2=81

Substituting the first three equations into the fourth allows us to solve for \lambda:

x^2+y^2+z^2=\dfrac1{4\lambda^2}+\dfrac1{4\lambda^2}+\dfrac1{4\lambda^2}=81\implies\lambda=\pm\dfrac1{6\sqrt3}

For each possible value of \lambda, we get two corresponding critical points at (\mp3\sqrt3,\mp3\sqrt3,\pm3\sqrt3).

At these points, respectively, we get a maximum value of f(3\sqrt3,3\sqrt3,-3\sqrt3)=9\sqrt3 and a minimum value of f(-3\sqrt3,-3\sqrt3,3\sqrt3)=-9\sqrt3.

Hi, could you help answer the questions in the image below?
ExtremeBDS [4]
In the second picture, top left is order 2, top right is order 4, bottom right is order 4, bottom left is order 2 I think but I'm not positive on that one. That's all I know for now, I'm currently in Calculus so my Geometry is a bit rusty.

PLEASE HELP QUICK!!!! What is the degree of 7x^6 - 6x^5 + 2x^3 + x - 8? A. 8 B. 7 C. 5 D. 6
antiseptic1488 [7]
For determining the correct degree of a polynomial, you need to look at each term and find the degree by adding the exponents of each variable in it. The largest degree is the degree of the polynomial.

7x^6 has largest degree of the given polynomial, so your answer is D.6

Please help me TwT<br> Please and Thank you!
Llana [10]

Answer:

Option C (None Of The Above)

Step-by-step explanation:

Given expression = -  (\frac{ - e}{ - f} )

Lets multiply the numerator and denominator by -1.

=  >  - ( \frac{ - e \times  - 1}{ - f \times  - 1} )

=  >  - ( \frac{e}{f} )

Now , lets open the brackets.

=  >  \frac{ - e}{f}

But as this expression is not there in the given options , the correct answer will be Option C.
