Which of the following equations belongs to an ellipse with vertical orientation?
Mekhanik [1.2K]

Answer:

d. 16x² + y² = 16

Step-by-step explanation:

Standard form of an ellipse is:

x² / a² + y² / b² = 1

If b > a, the ellipse has a vertical orientation.

We can ignore options b and c, since they have minus signs in them.

Convert the other options to standard form:

a. x² / (1/16) + y² / (1/25) = 1

x² / (1/4)² + y² / (1/5)² = 1

1/4 > 1/5

d. x² + y² / 16 = 1

x² / 1² + y² / 4² = 1

1 < 4

e. x² / 16 + y² = 1

x² / 4² + y² / 1² = 1

4 > 1

Of these three options, only d is a vertical ellipse.

Which statement about y = x2 − x3 is true?
ad-work [718]

ANSWER

c.It is neither an odd nor an even function.

EXPLANATION

The given function is

y = f(x) =  {x}^{2}  -  {x}^{3}

If this function is odd, then f(-a)=-f(a).

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

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

Now ,

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

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

Since

f( -  a) \ne - f(a)

The function is not odd.

Also if the function is even, then

f( a) =  f( - a)

Since

f( a) \ne  f( - a)

the function is not even.

Hence the function is neither even nor odd.
