Sagot :

To find the value of [tex]\( f(-3) \)[/tex] for the function [tex]\( f(x) = 2x + 10 \)[/tex], follow these steps:

1. Substitute [tex]\( x = -3 \)[/tex] into the function:
[tex]\[ f(-3) = 2(-3) + 10 \][/tex]

2. Perform the multiplication:
[tex]\[ 2(-3) = -6 \][/tex]

3. Add the result to 10:
[tex]\[ -6 + 10 = 4 \][/tex]

Thus, [tex]\( f(-3) = 4 \)[/tex].

The correct answer is [tex]\( \boxed{4} \)[/tex].
