I don’t know how to do question 3
antoniya [11.8K]

Answer:

The function y = -x whose reflection in the line y =x is itself.

Step-by-step explanation:

A reflection that maps every point of a figure to an image across a fixed line. Then the fixed line is called the line of reflection.

The reflection of the point (x,y)  in the line y = x is the point (y, x).

Therefore, the  function y = -x  whose  reflection in the line y =x is itself.

Symmetries of the function f(x)= -x is:    

A function symmetric with respect to the y-axis is called an even function.

If f(-x) = f(x)

A function that is symmetric with respect to the origin is called an odd function.

if f(-x) = -f(x)

then, we must look at f(-x);

f(x) = -x

f(-x)= -(-x)= x = -f(x)

this function is symmetrical to with respect to origin.

Therefore, this function is an odd function.

Check each true statement about the number 7- square root 3i
kumpel [21]

Answer:

option-A

option-D

Step-by-step explanation:

We are given a complex number as

7-\sqrt{3}i

we know that whenever we have

a+bi

where

a is the real number

b is imaginary number

now, we can verify each statement

option-A:

we can see that

a=7

and

a is the real number

so, 7 will be real number

so, this is TRUE

option-B:

we know that

b=-\sqrt{3}

so, imaginary number is -\sqrt{3}

while it is mentioned square root 3 is the imaginary part of the number

so, this is FALSE

option-C:

We can see that coefficient of  i is b

and

b=-\sqrt{3}

so, this is FALSE

option-D:

we know that

'a' and 'b' are sum of real and imaginary number

so, this is TRUE
