Unit activity: exponential and logarithmic functions
nirvana33 [79]

We will conclude that:

  • The domain of the exponential function is equal to the range of the logarithmic function.
  • The domain of the logarithmic function is equal to the range of the exponential function.

<h3>Comparing the domains and ranges.</h3>

Let's study the two functions.

The exponential function is given by:

f(x) = A*e^x

You can input any value of x in that function, so the domain is the set of all real numbers. And the value of x can't change the sign of the function, so, for example, if A is positive, the range will be:

y > 0.

For the logarithmic function we have:

g(x) = A*ln(x).

As you may know, only positive values can be used as arguments for the logarithmic function, while we know that:

\lim_{x \to \infty} ln(x) = \infty \\\\ \lim_{x \to0} ln(x) = -\infty

So the range of the logarithmic function is the set of all real numbers.

<h3>So what we can conclude?</h3>
  • The domain of the exponential function is equal to the range of the logarithmic function.
  • The domain of the logarithmic function is equal to the range of the exponential function.

PLZ ANSWER THIS CORRECTLY FOR 100 POINTS AND BRANLIEST :DD
gavmur [86]

Actually Welcome to the Concept of the Angles,.

Since,the AE is a angle bisector, hence, BAE = EAC simply.

hence we equate them..

===> x+ 30 = 3x - 10

==> 3x - x = 30 + 10

==> 2x = 40

==> x = 20°

hence the major angle EAC = 3(20)-10 = 60-10 = 50°

hence, angle EAC = 50°

If you add a constant to the original equation, you are actually shifting up or down

Since the constant is positive, you are shifting the graph 20 units up
