Exploring Parent Functions and Their Characteristics

This video tutorial covers major parent functions, including constant, linear, quadratic, cubic, absolute value, square root, reciprocal, exponential, and logarithmic functions. Each function is explained with its equation, graph, domain, and range. The video emphasizes understanding the characteristics of these functions to aid in transformations and graphing.

What is the range of a constant function f(x) = 5?

• y < 5

• y > 5

• y = 5

• All real numbers

In a linear function f(x) = x, what is the relationship between x and y?

• x is the square of y

• x is always greater than y
