Definition

h(t) represents Liam's height in inches at t years old according to the given model h(t) = 3t + 25. It is an equation that relates his age (independent variable) with his height (dependent variable).

Independent Variable: In this case, t is considered an independent variable since it represents Liam's age and can take on different values.

Dependent Variable: The dependent variable in this case is h(t), which depends on the values of the independent variable t. It represents Liam's height and changes as his age increases.

Linear Equation: h(t) = 3t + 25 is a linear equation because it has a constant rate of change (3) and does not involve any powers or roots.
