Question

Evaluate ƒ(x) = 3x + 8 for x = 1.

Answer 1

F equals 11 because it three times 1 plus eight.

Answer 2

Answer:  The required value of f(x) for x = 1 is 11.

Step-by-step explanation:  We are given to evaluate f(x) for x = 1, where

$f(x)=3x+8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To evaluate the required value, we need to substitute x = 1 in expression (i).

So, putting x = 1 in (i), we get

$f(1)=3\times1+8=3+8=11.$

Thus, the required value of f(x) for x = 1 is 11.
