Question

A math quiz has 10 questions and is scored out of 100. Each question is worth the same. The function S(q) represents the quiz score, S, in terms of the number of correctly answered questions, q.

What does S(q) represent in terms of its rate of change?
a) S(q) represents a quantity that changes at a constant rate per unit interval.
b) S(q) represents a quantity that changes at a constant percent rate per unit interval.
c) S(q) represents a linear function.
d) S(q) represents an exponential function.

Answer 1

The function S(q) represents the quiz score, S, in terms of the number of correctly answered questions, q. It represents a quantity that changes at a constant rate per unit interval, making it a linear function.

Step-by-step explanation:

The function S(q) represents the quiz score, S, in terms of the number of correctly answered questions, q. In this case, S(q) represents a quantity that changes at a constant rate per unit interval. This means that for every additional correctly answered question, the score increases by a fixed amount. So, S(q) is a linear function.
