What is the domain of the exponential function f(x) = 3 ^ x - 5

Answers

Answer 1
Answer:

Answer:

The domain of the exponential function f(x) = 3 ^ x - 5 is (-infinity, infinity)

What is the exponential function?

An exponential function is a mathematical function of the following form: f ( x ) = an x. where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e, which is equal to approximately 2.71828.

What is the exponential function formula?

Exponential Function Formula

An exponential function is defined by the formula f(x) = ax, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.

You have the numbers 1-25 written on slips of paper. if you choose one slip at random, what is the probability that you will select a number that is divisible by 5?3/5
4/25
1/5
8/25

Answers

To determine how many numbers from 1-25 that can be divisible by 5, let's count the multiples of 5 that go to 25.

5, 10, 15, 20, 25.

There are 5 multiples of 5 that are contained in 1-25.

Our current fraction is 5/25, as we have 5 multiples of 5, and 25 total numbers.

Since we don't have an answer choice that matches our answer, we may need to simplify.

Divide both sides by 5.

5 / 5 = 1
25 / 5 = 5

Our new and simplified answer is 1/5.

Your answer is C.) 1/5.

I hope this helps!

There are 5 numbers that are divisible by 5.

P(Div by 5) = 5/25 = 1/5

Given rectangular prism ABCD. Choose all of the terms that best describe each of the sets of lines or points. Points D, G and J collinear intersecting parallel noncollinear noncoplanar

Answers

Answer:

Step-by-step explanation:

The given parallelogram is attached.

First, we have to define some terms:

  • Collinear means that they are on the same line, non-collinear is the opposite.
  • Intersecting means that the point are touching each other, this apply to segments.
  • Parallel means that they will never intersect, because they have the same slope or inclination, this apply to lines also.
  • Coplanar means that points are in the same plane, non-coplanar is the opposite.

So, if we observe points D, G and J, from given options, they are non-collinear and non-coplanar, because they are not on the same line, nor plane.

Find the slope of the line through each pair of points (-7,13) (-15,-10)

Answers

Answer:

23/8

Step-by-step explanation:

Slope = Rise / Run

Rise = -10 - 13 = -23

Run = -15 - (-7) = -8

Slope = -23 / -8 = 23/8

Fine the value of a.

Answers

the value of a is 12 thanks have a nice day

Answer:   a = -3

==================================================

Work Shown:

The point (1, -3) is on the blue graph p(x) = a|x|

This means x = 1 and y = -3 pair up.

Use these two values to find 'a'

p(x) = a|x|

y = a|x|

-3 = a*|1|

-3 = a*1

-3 = a

a = -3

The negative 'a' value will apply the reflection over the x axis. The fact that |a| = 3 is larger than 1 indicates the graph is vertically stretched by a factor of 3.
