5)

Sketch the graphs of the functions f and g.
f(x) = x2, g(x) = 1/x2
 
Find the area of the region enclosed by these graphs and the vertical lines
x = 1 and x = 3.
 
 
= ? square units
The image contains four graphs comparing the functions \( f(x) = x^2 \) and \( g(x) = \frac{1}{x^2} \), depicted on a Cartesian plane with \( x \)- and \( y \)-coordinates ranging from \(-10\) to \(10\).

### Graph Descriptions:

1. **Top Left Graph:**
   - **Red Curve (f(x) = x^2):** This is a parabola opening upwards, crossing the y-axis at the origin (0,0).
   - **Blue Curve (g(x) = 1/x^2):** This hyperbola opens upwards and downwards, approaching the x-axis as an asymptote. It remains undefined at \( x = 0 \) and exhibits vertical asymptotic behavior.

2. **Top Right Graph:**
   - Red Curve (g(x) = -1/x^2): This hyperbola opens downwards, similar in shape to the inverse square but negatively mirrored.
   - Blue Curve (f(x) = x^2): Same parabola as in the first graph.

3. **Bottom Left Graph:**
   - **Red Curve (-1/x^2):** Part of this curve appears in the first quadrant, the rest in the second, mirroring the traditional hyperbola horizontally.
   - **Blue Curve (x^2):** Parabola with minimal visible adjustment in position.

4. **Bottom Right Graph:**
   - **Red Curve (1/x^2):** Identical to the first graph’s hyperbola behavior in shape, appearing in both the first and second quadrants.
   - **Blue Curve (x^2):** Parabola shown just as it appears in previous graphs.

### Observations:

- **Domain and Range:**
  - The domain of \( f(x) = x^2 \) includes all real numbers, while \( g(x) = \frac{1}{x^2} \) excludes \( x = 0 \).
  - The range of \( f(x) = x^2 \) is \( y \geq 0 \); \( g(x) = \frac{1}{x^2} \) has \( y > 0 \).

- **Asymptotic Behavior:**
  - \( g(x) = \frac{1}{x^2} \) tends towards infinity as \( x \
