Solution

Here is a transcription and breakdown of the problems from the image you uploaded:


1. Solve the following inequalities and express the solution set in three notations (interval notation, set notation, and on a number line):

a. x22x+26xx23x^2 - 2x + 2 \leq 6x - x^2 - 3 b. 2x+3>x3|2x + 3| > |x - 3|

2. If f(x)=x2f(x) = x^2, sketch the graph of the function g(x)=3x212x+16g(x) = 3x^2 - 12x + 16 by transforming the graph of f(x)f(x).

3. Given f(x)=2xx3f(x) = \frac{2x}{x - 3} and g(x)=2x5g(x) = \sqrt{2x} - 5, determine (fg)(x)(f \circ g)(x) and the domain DfgD_{f \circ g}.

4. Prove that limx23x+2=8\lim_{x \to 2} 3x + 2 = 8.

5. Compute limt0sin(2t)+5ttsec(t)\lim_{t \to 0} \frac{\sin(2t) + 5t}{t \cdot \sec(t)}.

6. Determine the horizontal and vertical asymptotes of the function:

a. f(x)=6x230x+362x22x12f(x) = \frac{6x^2 - 30x + 36}{2x^2 - 2x - 12}

7. Determine where the following function is not continuous:

\begin{cases} 2x^2 - 1, & x < -2 \\ 2x - 2, & -2 \leq x < 2 \\ 3x - x^2, & x \geq 2 \end{cases}$$ --- Would you like me to solve any of these problems in particular? Let me know if you'd like a detailed solution or have any specific questions! Here are 5 related questions to expand on these problems: 1. What are the steps involved in solving quadratic inequalities? 2. How do transformations like translation and scaling affect the graph of a function? 3. How do you compute the composition of two functions, and what affects their domain? 4. What are the conditions for proving a limit using the epsilon-delta definition? 5. How do you determine the vertical and horizontal asymptotes of rational functions? **Tip**: When working with inequalities involving absolute values, it's helpful to break them into different cases to handle the positive and negative parts separately.
