Answer :
To find [tex]\( f(3) \)[/tex] for the function [tex]\( f(x) = 58 - 9x \)[/tex], we need to substitute [tex]\( x = 3 \)[/tex] into the function and evaluate.
Here’s how to do it step-by-step:
1. Start with the function: [tex]\( f(x) = 58 - 9x \)[/tex].
2. Substitute [tex]\( x = 3 \)[/tex] into the function:
[tex]\[
f(3) = 58 - 9(3)
\][/tex]
3. Calculate the product [tex]\( 9 \times 3 \)[/tex]:
[tex]\[
9 \times 3 = 27
\][/tex]
4. Substitute the result back into the equation:
[tex]\[
f(3) = 58 - 27
\][/tex]
5. Perform the subtraction:
[tex]\[
58 - 27 = 31
\][/tex]
Therefore, [tex]\( f(3) = 31 \)[/tex]. The correct answer is 31.
