Answer: the first option! this is because one of the equations, x = y-4, is telling you what x equals. so in order to solve the equation, you need to substitute that into the x in the second equation
Right answer is:
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.
Step-by-step explanation:
Lets define the terms first
An independent variable is a variable whose values are put in the function. It is the input of a function.
While dependent variable's value depends on the independent variable.
Given function is:

By observing the function, we can see that the function is in terms of t which means that t is the input for the function while h is the name of the function. h(t) which be obtained by putting the values of t is the output.
So,
Right answer is:
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.
