Answer

linear; $g(x)=3x+5$

Work Step by Step

The ratio of consecutive values is not constant ($\frac{5}{2}\ne\frac{8}{5}$), hence, it is not an exponential function. The difference of consecutive values is constant, hence it is a linear function. The difference of consecutive values is $3$, hence the coefficient of $x$ (or slope) is $3$. Since $f(0)=5$, then the $y$-intercept is $5$. Thus, the slope-intercept form of the linear function that models the data is $g(x)=3x+5.$
