Question

When the function f(x) = 4x-2 is evaluated for x = 3, the output is:

4
6
16
None of the choices

Answer 1

Put 3 in for x:

f(3)= 4(3)-2
f(3)= 12-2
f(3)= 10
The output is 10 which is none of those.

Hope this helps. Have a wonderful day/night! :)

Answer 2

• Given - a function f (x) = 4x - 2

Here , we just need to substitute the value of x by 3. So ,

`\bold{f(x) = 4x - 2 }\\\bold{ f(3) = 4(3) - 2} \\ \bold{ ⇢ 12 - 2} \\ \bold{ ⇢ 10}`
