📖 1. Linear Function Evaluation

🔑 Key Concepts & Definitions

• Linear function: A function that graphs as a straight line, where the output changes at a constant rate with respect to the input. (see source content)

• General form of linear function: The algebraic expression representing a linear function, written as y = mx + b, where m is the slope and b is the y-intercept. (see source content)

• Slope (m): The rate of change of the function, indicating how much y increases or decreases for a unit increase in x. (see source content)

• Y-intercept (b): The point where the line crosses the y-axis, representing the value of y when x = 0. (see source content)

• Function notation g(x): A way to denote the output of a function g at a specific input x, meaning g(x) is the value of the function when x is substituted into the expression. (see source content)

📝 Essential Points

• To evaluate a linear function at any x value, substitute the given x into the function's algebraic expression. For example, if g(x) = -3x + 4, then g(1) = -3(1) + 4. This process allows you to find the specific output corresponding to a particular input.
