Question

If f(x) = |x + 8|, find f(−11)

Answer 1

\[f(\spadesuit)=|\spadesuit +8|\] and so
\[f(-11)=|-11+8|\]

Answer 2

so 19 right?

Answer 3

no

Answer 4

first you need \(-11+8\) or \(8-11\)
then you need to take the absolute value of that number

Answer 5

so its 3 right?

Answer 6

-11+8 is -3

| -3 | means make what is inside the | | positive
you get
|-3|= 3
so yes, the answer is 3.
