To graph the exponential function \( y = 0.5(6)^x \), we first identify the y-intercept. The y-intercept occurs when \( x = 0 \).
-
Substitute \( x = 0 \) into the function:
\[ y = 0.5(6)^0 \]
-
Since \( (6)^0 = 1 \):
\[ y = 0.5 \cdot 1 = 0.5 \]
Therefore, the y-intercept of the function \( y = 0.5(6)^x \) is \( 0.5 \).
The correct response is:
0.5
