1. dependent variable
2. independent variable 3. initial value
4. rate of change
a. the variable used for the output of a function
b. the variable used for the input of a function
c. a measure of how quickly or slowly the dependent value changes in comparison to the independent variable
d. the output value when the input value is zero in a real-world context

1. a

2. b

3. d

4. c

Explanation:

1. Dependent variable : a. The variable used for the output of a function

2. Independent Variable: b. The variable used for the input of a function

3. Initial Value: d. The output value when the input value is zero in a real-world context

4. Rate of change: c. A measure of how quickly or slowly the dependent value changes in comparison to the independent variable

Dependent variable refers to the variable whose value is dependent on another variable, unlike in case of independent variable.

Initial value refers to the value at the start or zero period.

Rate of change refers to the magnitude of change in dependent value with respect to independent variable.

answer; the above statement/question is ( true);

answer: marginal utility of the fourth brownie is 0.

explanation: marginal utility is the addtional utility gained from the consumption of one more unit of a good. it is given by,

so, marginal utility at the 4th unit will be given by

since, the values are not given here, you can simply find marginal utility at fourth unit by subtracting total utility at 3rd unit from total utility at 4th unit.
