Answer 1

@sammixboo
@dan815
can you help?

Answer 2

remember the value in the mod lines is always positve
eg |-5| = 5

Answer 3

Yes, I know. I just have no clue how to solve these kinds of problems :/

Answer 4

when ever you see "|" that means there is two sides of the equation

Answer 5

f(x)
f(2)

So that means x = 2 in this situation, so plug in 2 where x is and solve, right? I haven't done functions in a while xD

Answer 6

2 - 5 = -3
| -3| = 3

Answer 7

(replace the x in the function by 2)

Answer 8

f(2) = |2 − 5| + 3
right? so where do I go from there?

Answer 9

f(x) = | x - 5| + 3
f(2) = | 2 - 5| + 3

Answer 10

= | -3| + 3

Answer 11

so that'd be 6?

Answer 12

yes
3 + 3

Answer 13

f(2) = 6? so 6 is the answer?

Answer 14

yes

Answer 15

Thank you so much you helped a lot.

Answer 16

f(2) simply means the value of f(x) when x = 2
