Help? Please? :-)

Answer 1

replace x by 2

Answer 2

f(2) mean that x = 2 so then u can substitute into x

Answer 3

If you need more help just mention my name :)

Answer 4

by absolute value rules we either have
f(x) = x-5+3
f(x) = x-2
f(2) = 0

or

f(x) = -x+5+3
f(x) = -x+8
f(2) = 6

Answer 5

or.. we can just directly subsitute it and take the absolute value
f(x) = [x-5]+3
f(2) = [2-5]+3
f(2) = [-3]+3
f(2) = 3+3 =6

Answer 6

Thank you guys for all your help :)
