The function f(t) = 5 (4)^t represents the number of frogs in a pond after t years. If this function is graphed, what would be the meaning of the y-intercept? The pond starts off with 4 frogs

The number of frogs multiplies by 4 each year

The pond starts off with 5 frogs

After the first year, there are 20 frogs

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
