Question

Use the following function rule to find f(2). f(x) = 4 ( 9 ) x + 6 f(2) =

Answer 1

To find \( f(2) \) using the function rule \( f(x) = 4(9)x + 6 \), let's substitute \( x = 2 \) into the equation.

\[
f(2) = 4(9)(2) + 6
\]

Now calculate \( 4(9)(2) \):

\[
4(9)(2) = 4 \times 9 \times 2 = 36 \times 2 = 72
\]

Now, add 6:

\[
f(2) = 72 + 6 = 78
\]

So, \( f(2) = 78 \).
