Taylor earned the following amount each day.
• one dollar of the first day
• three dollars on the second day
• nine dollars on the third day
• twenty-seven dollars on the fourth day
Which function represents Taylor's daily earnings as a function of the number of days, t?
A f(x) = 3+1
B f(x) = 3
f(x) = 3t
D f(x) = 3-1

Answer 1

• f(t) = 3^(t - 1)

Explanation:

• one dollar of the first day = 3^0
• three dollars on the second day = 3^1
• nine dollars on the third day = 3^2
• twenty-seven dollars on the fourth day = 3^3

Numbers increase 3 times a day, it is an exponential function, powers of 3

The function is going to be:

• f(t) = 3^(t - 1)

Options are not clear, it seems to be D
