Sure, here are some step-by-step solutions using LaTeX: 1. Simplifying expressions: \begin{enumerate} \item Identify terms with common factors. \item Factor out the common factor. \item Simplify the resulting expression. \end{enumerate} 2. Solving equations: \begin{enumerate} \item Isolate the variable on one side of the equation. \item Use inverse operations (addition, subtraction, multiplication, division) to simplify the equation. \item Check the solution by plugging it back into the original equation. \end{enumerate} 3. Graphing functions: \begin{enumerate} \item Identify the domain and range of the function. \item Determine the intercepts (x-intercept and y-intercept). \item Find the critical points (where the function is undefined or changes direction). \item Plot the points and sketch the graph, connecting the points with smooth curves. \end{enumerate} 4. Calculating derivatives: \begin{enumerate} \item Apply the power rule or product rule (depending on the type of function). \item Simplify the resulting expression. \item Evaluate the derivative at a specific point (if necessary). \end{enumerate} 5. Solving word problems: \begin{enumerate} \item Read the problem carefully and identify what is given and what is asked. \item Translate the problem into a mathematical equation or expression. \item Solve the equation or expression using the appropriate method. \item Check the solution by verifying that it makes sense in the context of the problem. \end{enumerate}
