Question

If: f(x) = 4x-2
Find f(2)

Answer 1

f(2)=6

Explanation:

1) Since 2 is substituting the x, we are going to do the same for the expression 4x-2. 4(2)-2

2) We are going to simplify the equation using the distributive property and order of operations, you get 6. This means that f(2)=6.

Answer 2

6

Explanation:

We are given:

f(x)=4x-2

and are asked to find the answer when f(2)

We can see that the 2 replaces x in the original equation, so we are asked to find what the answer is when x=2

To start, replace x with 2:

f(2)=4(2)-2

multiply

f(2)=8-2

simplify by subtracting

f(2)=6

So, when f(2), the answer is 6.

Hope this helps! :)
