1 )
f ( - 10 ) = | - 10 + 6 | = | - 4 | = 4
Answer: D ) 4
2 )
f ( 1 ) = | 1 - 4 | + 5 = | - 3 | + 5 = 3 + 5 = 8
Answer: A ) 8
3 )
f ( - 6 ) = 8 - 3 * | - 6 + 2 | = 8 - 3 * | - 4 | = 8 - 3 / 4 = 8 - 12 = - 4

What you need to do just plug the number into the x values in the function. 

1. f(x) = x + 6 
f(-10) = -10 + 6 = -4
The answer is C. -4

2.  f(x) = (x − 4) + 5
f(1) = (1 - 4) + 5 
= (-3) + 5 = 2
The answer is B. 2

3. f(x) = 8 − 3(x + 2)
f(−6) = 8 - 3(-6 + 2)
= 8 - 3(-4)
= 8 + 12 = 20
The answer is A. 20

Explain how to find the estimated sum of <br><br><br> 5<br> 8<br> +<br> 2<br> 9<br> .
mina [271]

The estimated sum of the numbers fifty-eight (58) and twenty-nine (29) is equal to ninety (90).

<h3>What is the difference between a regular sum and an estimated sum?</h3>

In an estimated sum, the numbers are rounded; on the other hand, in a regular sum, the numbers are not changed.

<h3>What is the estimated sum of 58 and 29?</h3>

1. Round the numbers:

  • 58 = 60 as this number is nearest to 60 than to 58.
  • 29= 30 because of the same reason explained above.

2. Add the rounded numbers:

  • 60 + 30 = 90

Compute the second partial derivatives ∂2f ∂x2 , ∂2f ∂x ∂y , ∂2f ∂y ∂x , ∂2f ∂y2 for the following function. f(x, y) = 2xy (x2 +
blsea [12.9K]

Answer with step-by-step explanation:

We are given that a function

f(x,y)=2xy(x^2+y^2)^2

Differentiate partially w.r.t x

Then, we get

\frac{\delta f}{\delta x}=2y(x^2+y^2)^2+8x^2y(x^2+y^2)=(x^2+y^2)(2x^2y+2y^3+8x^2y)=2(5x^2y+y^3)(x^2+y^2)

Differentiate again w.r.t x

\frac{\delta^2f}{\delta x^2}=2(10xy)(x^2+y^2)+4x(5x^2y+y^3)=20x^3y+20xy^3+20x^3y+4xy^3=40x^3y+24xy^3

Differentiate function w.r.t y

\frac{\delta f}{\delta y}=2x(x^2+y^2)^2+2xy\times 2(x^2+y^2)\times 2y

\frac{\delta f}{\delta y}=(x^2+y^2)(2x^3+2xy^2+8xy^2)=2(x^2+y^2)(x^3+5xy^2)

Again differentiate w.r.t y

\frac{\delta^2f}{\delta x^2}=2(2y)(x^3+5xy^2)+20xy(x^2+y^2)=4x^3y+20xy^3+20x^3y+20xy^3=24x^3y+40xy^3

Differentiate partially w.r.t y

\frac{\delta^2f}{\delta y\delta x}=2(2y(5x^2y+y^3)+(x^2+y^2)(5x^2+3y^2))=10x^4+36x^2y^2+10y^4

\frac{\delta^2f}{\delta y\delta x}=10x^4+36x^2y^2+10y^4\frac{\delta^2f}{\delta x\delat y}=2(2x(x^3+5xy^2)+(3x^2+5y^2)(x^2+y^2))=10x^4+36x^2y^2+10y^4

\frac{\delta^2f}{\delta x\delat y}=10x^4+36x^2y^2+10y^4

Hence, if f(x,y) is of class C^2 (is twice continuously differentiable), then the mixed partial derivatives are equal.

i.e\frac{\delta^2f}{\delta y\delta x}=\frac{\delta^2f}{\delta x\delta y}

1. {(0, 2), (4, 2), (3, 2), (5, 1), (6, 2)}
o-na [289]
A) The domain of this relation would be 0,4,3,5, and 6. These are our possible x values for the function. Since this equation doesn't tell us to assume that it's a function then it's fine for us to list them separately.
B) The range of this function is 2 and 1. This is for the same reasons listed in A.
C) This can be a function because although it has the same y-values several times, the x values are always different. This would not be a linear function though, since the slope should be zero, and the value (5,1) would come off of the function y=2.
