To find the y-intercept of the exponential function \( y = 8(4^x) \), we need to evaluate the function at \( x = 0 \).
Substituting \( x = 0 \) into the function:
\[
y = 8(4^0)
\]
Since \( 4^0 = 1 \):
\[
y = 8(1) = 8
\]
Thus, the y-intercept is \( 8 \).
Substituting \( x = 0 \) into the function:
\[
y = 8(4^0)
\]
Since \( 4^0 = 1 \):
\[
y = 8(1) = 8
\]
Thus, the y-intercept is \( 8 \).
