Final answer:
The correct description of the function h(t) = 210 – 15t is that 'h' represents the function name, 't' is the independent variable, and 'h(t)' is the dependent variable. The independent variable is graphed on the x-axis, whereas the dependent variable is graphed on the y-axis.
Step-by-step explanation:
The correct statement that best describes the function h(t) = 210 – 15t is: 'h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.' In the context of a linear equation such as this, the independent variable is the one that can be set freely, often representing a cause, while the dependent variable represents the effect or outcome that depends on the independent variable.
In a graph of a function, the independent variable is typically placed on the horizontal axis (x-axis), and the dependent variable is on the vertical axis (y-axis). The slope of the equation represents the rate of change of the dependent variable with respect to the independent variable, and the y-intercept is the value of the dependent variable when the independent variable is zero.
