Answer:

63.5°

Step-by-step explanation:

By inscribed angle theorem:

$m\angle XYZ=\frac{1}{2} \times m\widehat {XZ}$

$\therefore m\angle XYZ=\frac{1}{2} \times 127\degree$

$\therefore m\angle XYZ=63.5\degree$

What is the domain of f(x) = 2^x?

hammer [34]

The given function has no undefined points nor domain constraint. Thus, the domain is: $-\infty \: < x < \infty$ .

<h3>Domain and Range</h3>

The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. An example, there is a restriction for the domain of fractions. The variable x in the denominator should be different of zero.

While the domain is related to the values of x, the range is related to the possible values of y that the function can have.

In this question, the function $2^x$ has no undefined points nor domain constraint. Therefore, the domain is: $-\infty \: < x < \infty$
