\bf ~~~~~~~~~~~~\textit{negative exponents}
\\\\
a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad 
a^n\implies \cfrac{1}{a^{-n}}
\\\\
-------------------------------

\bf \cfrac{2x^{-\frac{7}{4}}}{4x^{\frac{4}{3}}}\implies \cfrac{2}{4}\cdot \cfrac{x^{-\frac{7}{4}}}{x^{\frac{4}{3}}}\implies \cfrac{1}{2}\cdot \cfrac{1}{x^{\frac{4}{3}}\cdot x^{\frac{7}{4}}}\implies \cfrac{1}{2}\cdot \cfrac{1}{x^{\frac{4}{3}+\frac{7}{4}}}\implies \cfrac{1}{2}\cdot \cfrac{1}{x^{\frac{16+21}{12}}}
\\\\\\
\cfrac{1}{2}\cdot \cfrac{1}{x^{\frac{37}{12}}}\implies \cfrac{1}{2x^{\frac{37}{12}}}

I need help figuring out when to use law of sine or law of cosine?
irina [24]
When you have angle and its corresponding (opposite) side then you need to use law of  sin. Problems 3,4,5(in 5 you need at first find angle X=180-92-62)


when you have two sides and angle between them, this is law of cos, problem 6,8

problem 7 you can use both, but if you can use both better to use law of sin, it is just easier

Use the description and table to graph the function, and determine the domain and range of f(x). Represent the domain and range
zmey [24]

The domain of the function is x > 0 and the range of the function is -∞ < f(x) < ∞

<h3>How to determine the domain?</h3>

The table represents a logarithmic function.

The domain represents the set of x values.

From the table, we can see that all the x values are positive values i.e. x > 0

Hence, the domain of the function is x > 0

<h3>How to determine the range?</h3>

From the table, the table outputs all zero, positive and negative numbers

This means that the range is the set of all real numbers.

Hence, the range of the function is -∞ < f(x) < ∞
