Question

Use the following function rule to find f(2).

f(x) =
7.9
( 10 )
x


Write your answer as a decimal or whole number.

Answer 1

To find \( f(2) \) using the function rule \( f(x) = 7.9 \cdot (10)^x \), we will substitute \( x = 2 \) into the function.

\[
f(2) = 7.9 \cdot (10)^2
\]

Now, calculate \( (10)^2 \):

\[
(10)^2 = 100
\]

Now plug this value back into the equation:

\[
f(2) = 7.9 \cdot 100
\]

Now, multiply:

\[
f(2) = 790
\]

Thus, the value of \( f(2) \) is \( 790 \).
