If [tex]f(x) = 2x + 1[/tex], what is [tex]f(-3)[/tex]?

f ( x ) = 2 x + 1 x = − 3 f ( − 3 ) = 2 ⋅ ( − 3 ) + 1 = − 6 + 1 = − 5

This just means substitute -3 as x, so its -5

To find f ( − 3 ) for the function f ( x ) = 2 x + 1 , we substitute − 3 into the equation. This results in f ( − 3 ) = − 5 . Therefore, the final answer is − 5 .
