Question

The equation of a function F is shown.
f(x)=-2(3)^(x)

find f(4)
f(4)=__

Answer 1

To find \( f(4) \) for the function given by \( f(x) = -2(3)^x \), you can substitute \( x \) with \( 4 \):

\[
f(4) = -2(3)^4
\]

Now, calculate \( 3^4 \):

\[
3^4 = 81
\]

Now substitute this back into the function:

\[
f(4) = -2 \cdot 81 = -162
\]

Thus, the value of \( f(4) \) is:

\[
\boxed{-162}
\]
