Question

Let f(x) = 3x, x<2

x+10, 27 Explain the process you would go through to find f(8)

Answer 1

x=8>7
=> f(x)= 2-x = 2-8 = -6

Answer 2

Can you please explain why its is X>7 ?

I am having trouble figuring out what to do with x+10, 2\[2lex \le7\]

Answer 3

\[2 \le x \le 7\]

Answer 4

f(x)= 3x for x<2
f(x) = x+10 for 2<x<7
f(x)= 2-x for x>7
here you need to find f(8) then you must replace x=8
and since 8>7 then you use the third equation f(x)=2-x

Answer 5

Thank you so much for clearing that up!
