Question

-----PART 2 (Part 1 is in a different post, this is the last part----

Consider the function \( f(x) = 2x + 1 \). Now, find \( f(3) \) and evaluate \( f(3) + f(5) \). What is the final result?

(ignore the / it is from ChatGPT)

Answer 1

2(3)=6, 6+1=7

f(3)=7

2(5)=10, 10+1=11

f(5)=11

f(3)+f(5)=18

Answer 2

Uh, 8f?

To find \( f(3) \), substitute \( x = 3 \) into the function: \( f(3) = 2(3) + 1 = 7 \).

Now, evaluate \( f(3) + f(5) \): \( 7 + (2(5) + 1) = 7 + 11 = 18 \). The final result is 18.

Good try though!

Okay.
