The sequence below shows the total number of days Frank had used his gym membership at the end of weeks 1, 2, 3, and 4.
            4, 9, 14, 19, ...
Assuming the pattern continued, which function could be used to find the total number of days Frank had used his gym membership at the end of week n? 

• f(n) = n + 5 
• f(n) = 5n – 1 
• f(n) = 5n + 4 
• f(n) = n2

There were originally 4 trees in an orchard. Each year the owner planted the same number of trees. In the 29th year, there were 178 trees in the orchard. Which function, t(n), can be used to determine the number of trees in the orchard in any year, n? 

• t(n)=(178/29)n + 4
• t(n)=(178/29)n - 4
• t(n)=6n + 4
• t(n)= 29n - 4

The function is _______

• linear

• quadratic

• exponential

The y-intercept is ________

• ( 1, 15 )

• ( 0, 1 )
