The function f(x) = 2x + 5 represents the grade a student achieves on a test f(x) based on the number of hours they study (x). Explain in words what this function means in terms of the student's grade and study time.
A student finds that studying with a group helps them understand the material better. The function g(x) = (x - 3) / 4 represents the average amount of time spent on each problem, where x is the total study time in minutes. Describe in words how the total study time (x) relates to the average time spent on each problem, according to the function g(x).

Quick comprehension check
“The function f(x) = 5x + 2 represents a singer's earnings (f(x)) based on the number of songs they sell online (x). Describe in words what this function means in terms of the singer's earnings and song sales. A student is saving money for a new phone. The function g(x) = (x - 10) / 5 represents the number of weeks it will take to save enough money, where x is the total amount of money needed. Describe in words how the total amount of money needed (x) relates to the number of weeks it will take to save, according to the function g(x). Write a function, h(x), that represents the following: "Multiply the input by 4, then subtract 10 from the result."”
