Explanation

If a set A has m elements and set B has n elements,

then the number of functions possible from A to B is n^m.

Explanation

x + y^2 = 1 is symmetric with the  x-axis

Let's look at the graph of 

x + y^2 = 1 about the  x− and y-axis and the lines y = x and y = − x below.

graph{(x+y^2-1)(y-x)(y+x)=0 [-10, 10, -5, 5]}

X + y^2= 1 is symmetric with the x-axis 

Explanation

1. Center:

To check for symmetry, we first need to identify the center of the graph.

The equation is in the form of a circle, x^2 + y^2 = 1, which has its center at the origin (0,0).

2. x-axis symmetry:

A graph is symmetric about the x-axis if replacing y with -y in the equation does not change the equation.

Let's test this:

x^2 + (-y)^2 - x = 1

x^2 + y^2 - x = 1

As we can see, the equation remains the same, so the graph is symmetric about the x-axis.

Explanation

To solve this equation, we can set up a proportion:

x/y = y/1

To solve for x, we can cross-multiply:

x = y * y / 1

Simplifying this expression, we have:

x = y^2

Explanation

On 2 January 1965, Fatima Jinnah was a presidential candidate against Ayub Khan

There were four candidates: 

• Ayub Khan
• Fatima Jinnah
• and two obscure people with no party affiliation. 

Laltain was the election symbol of Fatima Jinnah 

Additional Information

Fatima Jinnah: younger sister of Quaid-e-Azam Muhammad Ali Jinnah

She was born: 30th July 1893

She is referred to as Madr-e-Millat (Mother of Nation)

She died on 9 July 1967 at the age: of 71 in Karachi

Explanation

Active: "A nice present was given to Sue by Esther."

Passive: Sue was given a nice present by Esther.

In this sentence, the subject ("Esther") becomes the object in the passive sentence,

and the direct object ("a nice present") becomes the subject in the passive sentence.

The verb "gave" changes to "was given" in the passive voice,

Active and the preposition "to" is used to indicate the recipient of the action ("Sue").
