Answer:

The correct answer is A. >

Step-by-step explanation:

The first thing to take into account is that the sign  |  | refers to absolute value. The absolute value consists of making any number inside positive. It doesn't matter if the number inside is positive or negative the result will be always positive. Let's see an example.

|8|=8

|-8|=8

As you can see, the result for |8| is the same for |-8| which is 8.

With that in time, let's make the same procedure for |-18.25|\, \, \, \, \, |10.75|

According to the previous the first and second numbers would be:

  1. |-18.25|=18.25
  2. |10.75|=10.75

As 18.25 is higher than 10.75 (18.25 > 10.75), the answer is |-18.25|>|10.75|.

Thus, the correct answer is A. >

The absolute value of any number is its <em>distance from 0</em>. -18.25 is 18.25 units from 0, so |-18.25| = 18.25, and by similar thinking, |10.75| = 10.75. Since 18.25 is bigger than 10.75, we can write |-18.25| > |10.75|

What best describes the asymptote of an exponential function of the form f(x)=b^x?
horrorfan [7]

It depends on the value of b


Exponential functions are defined for positive values of the base [ŧex] b [/tex]. Also, they're not defined if b=1, or at least let's say that this is a trivial case, since it is the constant function 1.


Case 0<b<1:

If the base sits between 0 and 1, the exponential function is constantly decreasing. The explanation is quite intuitive, assume for the sake of simpleness that b is rational. If it sits between 0 and 1, it means that it can be written as a fraction p/q, with p<q. So, if you give a large exponent to b, you obtain


\frac{p^x}{q^x},\quad p^x \ll q^x \text{ as } x \to \infty


On the other hand, if you consider negative exponents, you switch numerator and denominator and then raise to the same exponent the fraction q/p, which gets larger and larger.


So, if 0<b<1, we have


\lim_{x \to -\infty} b^x = \infty,\qquad \lim_{x \to \infty} b^x = 0


and thus 0 is a horizontal asymptote as x tends to (positive) infinity.


Case b>1:

This case is very similar, except all roles are inverted. Now you start with a fraction p/q where p>q. So, with positive, large exponents you get


\frac{p^x}{q^x},\quad p^x \gg q^x \text{ as } x \to \infty


And as before, negative exponents switch numerator and denominator, so the fraction becomes q/p and thus you have


\lim_{x \to -\infty} b^x = 0,\qquad \lim_{x \to \infty} b^x = \infty


So, again, 0 is a horizontal asymptote, but this time for x tending towards negative infinite.

What is the slope of the line ?
atroni [7]

Answer:

-2\frac{2}{3}

Step-by-step explanation:

The line passes through points (1,4) and (4,-4)

Slope (m) = change in y ÷ change in x

i.e m = \frac{-4 - 4}{4 - 1} = \frac{-8}{3} = -2\frac{2}{3}

What is the inverse of f(x)=3x+6 ?
scZoUnD [109]

Answer:

\boxed{\sf \ \ f^{-1}(x)=\dfrac{x-6}{3} \ \ }

Step-by-step explanation:

hello,

we can write

fof^{-1}(x)=x \ and \ fof^{-1}(x)=f(f^{-1}(x))=3f^{-1}(x)+6 \ so\\3f^{-1}(x)+6=x \ \ subtract \ 6\\3f^{-1}(x)=x-6 \ \ divide \ \ by \ \ 3\\ f^{-1}(x)=\dfrac{x-6}{3}

hope this helps
