1. **Problem:** Graph the equation $y = -3x + 2$, determine domain and range, and analyze function properties.
2. **Formula and rules:** This is a linear function of the form $y = mx + b$ where $m$ is slope and $b$ is y-intercept.
3. **Domain:** For linear functions, domain is all real numbers, $\mathbb{R}$.
4. **Range:** Also all real numbers, $\mathbb{R}$, since line extends infinitely.
5. **Function check:** Each $x$ maps to exactly one $y$, so it is a function.
6. **One-to-one check:** Since slope $m = -3 \neq 0$, function is one-to-one.
7. **Onto check:** The function covers all real $y$ values, so it is onto $\mathbb{R}$.
8. **Discrete or continuous:** The function is continuous because it is defined for all real $x$.
9. **Intermediate work:** None needed for linear function.
10. **Final answer:** Domain: $\mathbb{R}$, Range: $\mathbb{R}$, Function: yes, One-to-one: yes, Onto: yes, Continuous.

1. **Problem:** Graph the equation $y = 2x^2$, determine domain and range, and analyze function properties.
2. **Formula and rules:** Quadratic function $y = ax^2$ with $a=2$.
3. **Domain:** All real numbers, $\mathbb{R}$.
4. **Range:** Since $a>0$, parabola opens upward, minimum at $y=0$, so range is $[0, \infty)$.
5. **Function check:** Each $x$ has one $y$, so function.
6. **One-to-one check:** Not one-to-one because $f(x) = f(-x)$.
7. **Onto check:** Not onto $\mathbb{R}$ because $y<0$ values are not reached.
8. **Discrete or continuous:** Continuous over $\mathbb{R}$.
9. **Final answer:** Domain: $\mathbb{R}$, Range: $[0, \infty)$, Function: yes, One-to-one: no, Onto: no, Continuous.

1. **Problem:** Evaluate $g(\frac{2}{3})$ for $g(x) = -2x^2$.
2. **Calculation:**
$$g\left(\frac{2}{3}\right) = -2\left(\frac{2}{3}\right)^2 = -2\left(\frac{4}{9}\right) = -\frac{8}{9}$$

1. **Problem:** Evaluate $h(\frac{1}{5})$ for $h(x) = -4x^2 - 2x + 5$.
2. **Calculation:**
$$h\left(\frac{1}{5}\right) = -4\left(\frac{1}{5}\right)^2 - 2\left(\frac{1}{5}\right) + 5 = -4\left(\frac{1}{25}\right) - \frac{2}{5} + 5 = -\frac{4}{25} - \frac{2}{5} + 5$$
Convert to common denominator 25:
$$-\frac{4}{25} - \frac{10}{25} + \frac{125}{25} = \frac{-4 - 10 + 125}{25} = \frac{111}{25} = 4.44$$
3. **Final answer:** $h(\frac{1}{5}) = \frac{111}{25}$ or approximately 4.44.
