The expression 4*3^(t) gives the number of ducks living in Anoop's pond t years after he built it. What does 4 represent in this expression? Choose 1 answer: (A) It has been 4 years since Anoop built the pond. (B) The number of ducks living in Anoop's pond is multiplied by 4 every year. (c) There were 4 ducks living in Anoop's pond when he first built it.

Exponential function definition: The expression 4*3^(t) is an exponential function where t is the exponent and represents the number of years after Anoop built the pond. To understand what the number 4 represents, we need to consider the value of the expression when t = 0, which is the time Anoop built the pond.Substituting t = 0: Substitute t = 0 into the expression to find the initial number of ducks. The expression becomes 4*3^(0). Since any number raised to the power of 0 is 1, we have 3^(0) = 1.Calculating the initial number of ducks: Now, calculate the number of ducks when t = 0. The expression simplifies to 4*1, which equals 4. This means that when Anoop first built the pond, there were 4 ducks in it.Interpreting the meaning of 4: Based on the calculation, the number 4 in the expression 4*3^(t) represents the initial number of ducks in Anoop's pond when he first built it. Therefore, the correct answer is (C) There were 4 ducks living in Anoop's pond when he first built it.

ducks living in Anoop's pond when he first built it.

Exponential function definition: The expression $4 \cdot 3^{t}$ is an exponential function where $t$ is the exponent and represents the number of years after Anoop built the pond. To understand what the number $4$ represents, we need to consider the value of the expression when $t = 0$ , which is the time Anoop built the pond.
Substituting $t = 0$ : Substitute $t = 0$ into the expression to find the initial number of ducks. The expression becomes $4 \cdot 3^{0}$ . Since any number raised to the power of $0$ is $1$ , we have $3^{0} = 1$ .
Calculating the initial number of ducks: Now, calculate the number of ducks when $t = 0$ . The expression simplifies to $4 \times 1$ , which equals $4$ . This means that when Anoop first built the pond, there were $4$ ducks in it.
Interpreting the meaning of $4$ : Based on the calculation, the number $4$ in the expression $4 \cdot 3^{t}$ represents the initial number of ducks in Anoop's pond when he first built it. Therefore, the correct answer is (C) There were $4$ ducks living in Anoop's pond when he first built it.
