Answer:

None of the given option is correct.

Step-by-step explanation:

The expression given is:

-18-(-9)

= -18+9

= -9

Now checking the options, which will have -9 as answer

1) 0 -18+2

= -18+2

= -16

As answer is not -9, so this is not a correct option

2) 9 -12-(-3)

= 9 - 12 + 3

= 0

As answer is not -9, so this is not a correct option

3) -10-5

= -10-5

= -15

As answer is not -9, so this is not a correct option

So, None of the given option is correct.

Which of the following explains why f(x) = log2x

Radda [10]

Answer:

There is no power of 2 that is equal to 0.

Its inverse does not have any x-intercepts.

Step-by-step explanation:

Given the function

$\:\:f\left(x\right)=\log \:_2\left(x\right)$

This function can be written as:

$y=\log _2\left(x\right)$

As the rule tells s that

$\:y=log_ax\Rightarrow \:a^y=x$

$x=2^y\:\:$

As we know that the value of x=0 at y-intercept.

$0=2^y\:\:$

For any value of $y$ , this statement is false as there is no power of 2 that is equal to 0.

Also

Lets interchange x and y in the equation $x=2^y\:\:$ to find the inverse of the function.

$y=2^x\:\:$

So, it doesn't have any x-intercepts as for any value of x, the value of $y$ can not be zero for this function.

Therefore, Its inverse does not have any x-intercepts.
