Zach read a book for 10 minutes every weekend in the first month, 20 minutes in the second month, 40 minutes in the third month, and 80 minutes in the fourth month.
Victoria read a book for 35 minutes every weekend in the first month, 50 minutes in the second month, 65 minutes in the third month, and 80 minutes in the fourth month.
Which statement best describes the methods used by Zach and Victoria to increase the time they spent reading a book?
Zach's method is linear because the number of minutes increased by an equal factor every month.
Victoria's method is linear because the number of minutes increased by an equal number every month.
Both Victoria's and Zach's methods are exponential because the number of minutes increased by an equal factor every month.
Both Victoria's and Zach's methods are exponential because the number of minutes increased by an equal number every month.

Zach's method is exponential because the number of minutes doubled every month. Victoria's method is linear because the number of minutes increased by an equal number every month.
Two scientists are running experiments on the same type of friction in different control groups. The results are shown in the graph using the functions f(x) and g(x):
graph of two functions in quadrant 1, f of x equals 2 times x plus 3 and g of x equals one tenth times 3 to the x power
Which statement best describes the graph of f(x) and g(x)?
The graphs will both have their y-intercept equal to 3.
The graphs will both have their y-intercept equal to 4.
The graph of f(x) will eventually exceed the graph of g(x).
The graph of g(x) will eventually exceed the graph of f(x).
