To find \( f(1) \) using the function rule \( f(x) = -10(5)^x \), we will substitute \( x \) with \( 1 \).
\[
f(1) = -10(5)^1
\]
Calculating \( (5)^1 \):
\[
(5)^1 = 5
\]
Now, substitute this value back into the equation:
\[
f(1) = -10 \times 5
\]
Multiplying:
\[
f(1) = -50
\]
So, \( f(1) = -50 \).
\[
f(1) = -10(5)^1
\]
Calculating \( (5)^1 \):
\[
(5)^1 = 5
\]
Now, substitute this value back into the equation:
\[
f(1) = -10 \times 5
\]
Multiplying:
\[
f(1) = -50
\]
So, \( f(1) = -50 \).
