Answer :
Line 1 : Postive
Line 2 : Undefined
Line 3 : Zero
Line 4 : Negative

Explanation:

Look at the line. Starting from the left side, is it going up or down? Up means it is positive. Down means it is negative. The other two lines you just have to remember which one is undefined and which one is Zero.

Answer:

see explanation

Step-by-step explanation:

A line sloping upwards from left to right has a positive slope.

Line 1 is in this category.

A line sloping downwards from left to right has a negative slope.

Line 4 is in this category.

The slope of a vertical line, parallel to the y- axis is undefined.

Line 2 is in this category.

The slope of a horizontal line, parallel to the x- axis is zero.

Line 3 is in this category.

Find the critical point of the given function and then determine whether it is a local maximum, local minimum, or saddle point.

34kurt

Answer:

critical point of the given function f(x,y) = x²+y²+2xy is from line y = -x is the critical point of the function f(x0,y0) = 0

and it local minimum.

Step-by-step explanation:

Let the given function be;

f(x,y) = x²+y²+2xy

From above function, we can locate relative minima, maxima and the saddle point

f(x,y) = x²+y²+2xy = (x+y)²

df/dx = 2x+2y = 0 ---- (1)

df/dy =2y+2x = 0 ---- (2)

From eqn 1 and 2 above,

The arbitrary point (x0,y0) from line y = -x is the critical point of the function f(x0,y0) = 0

Then, from f(x,y) >= 0 for arbitrary (x,y) € R^n, the arbitrary point from the line x = -y is local minima of the function f.

If the function graphed is f(x), find f(1)

mihalych1998 [28]

Answer:

f(1)=-4

Step-by-step explanation:

f(1) means what is the y in the point on the curve of f so that x=1.

So I go to x=1 on the x-axis.

So I go right one from the origin.

I notice the curve is below the x-axis so I go down to the curve til I get to the curve.

Once I get to the curve, I look at the y-axis to tell what that number is for that ordered pair there at x=1.

That y-value is -4.

A graph/picture is probably worth a lot more to you then my words.

Other examples:

f(2)=-5

f(3)=0

f(-1)=4

f(-2)=5

f(-3)=0
