How is unit analysis helpful in solving real-life problems?

Evaluate the expression for the given value of the variable. $$x^{4}-3 \text { when } x=2$$

Decide whether the following is an expression, an equation, or an inequality. Explain your decision. $$5 x-1=3+x$$

For a relationship to be a function, it must be true that for each input, there is exactly one output. Does the table represent a function? Explain. $$ \begin{array}{|c|c|} \hline \text { Input } & \text { Output } \\ \hline 1 & 3 \\ \hline 2 & 4 \\ \hline 3 & 5 \\ \hline 4 & 6 \\ \hline \end{array} $$

Match the verbal phrase with its corresponding algebraic expression. A. \(4 x-11\) B. \(4(x-11)\) c. \(11-4 x\) D. \(11 x+4\) Eleven decreased by the quantity four times a number \(x\)
