To find the y-intercept of the function \( y = 3(2)^t \), we need to evaluate the function at \( t = 0 \):
\[ y = 3(2)^0 \]
Since \( 2^0 = 1 \), we have:
\[ y = 3 \cdot 1 = 3 \]
Thus, the y-intercept is at the point \( (0, 3) \).
So, the final answer to your question is:
The y intercept is at \( (0, 3) \).
