To graph the function \( f(x) = \frac{1}{4}x + 2 \):
1. **Plot Points**:
- When \( x = 0 \), \( f(0) = 2 \). So, plot the point (0, 2).
- When \( x = 4 \), \( f(4) = 3 \). So, plot the point (4, 3).
- When \( x = -4 \), \( f(-4) = 1 \). So, plot the point (-4, 1).
2. **Draw the Line**:
- Connect these points with a straight line.
**Domain and Range**:
- **Domain**: All real numbers, represented as \( (-\infty, \infty) \).
- **Range**: All real numbers, represented as \( (-\infty, \infty) \).

The function given is
f(x) = (1/4)x + 2
Step 1: Graphing the Function
• The y-intercept occurs when x = 0. Plugging in:
f(0) = (1/4)(0) + 2 = 2.
So, the point (0, 2) is on the graph.
• The slope is 1/4, meaning that for every increase of 4 units in x, y increases by 1 unit. For example:
If x = 4, then f(4) = (1/4)(4) + 2 = 1 + 2 = 3, giving the point (4, 3).
Similarly, if x = -4, then f(-4) = (1/4)(-4) + 2 = -1 + 2 = 1, giving the point (-4, 1).
• Plot the points (0, 2), (4, 3), and (-4, 1) on a coordinate plane, and draw a straight line through them.
Step 2: Domain and Range
• Domain:
Since f(x) is a linear function (with no restrictions such as square roots or denominators that could cause division by zero), the domain is all real numbers.
In interval notation: Domain = (–∞, ∞).
• Range:
Since the line continues indefinitely in both the upward and downward directions (because the slope is non-zero), the range is also all real numbers.
In interval notation: Range = (–∞, ∞).
Summary:
• Graph: A straight line through points (0, 2) and (4, 3) (also through (-4, 1)).
• Domain: All real numbers, i.e., (–∞, ∞).
• Range: All real numbers, i.e., (–∞, ∞).
You can visualize the graph by plotting these points on a coordinate grid and drawing a line through them.

The Deep Dive
To graph the linear function \( f(x) = \frac{1}{4}x + 2 \), start by plotting the y-intercept at (0, 2). Since the slope is \( \frac{1}{4} \), for every 4 units moved to the right on the x-axis, move up 1 unit on the y-axis. Connect the points for a straight line that extends infinitely in both directions. For the domain, since this is a linear function, the domain is all real numbers, or \( (-\infty, \infty) \). The range is also all real numbers, given the nature of linear functions, so the range is \( (-\infty, \infty) \) as well.
