Question

Let f(x) = x + 4, x ≤ −3
sqaure root( 9 − x2) , −3 < x ≤ 3
−x + 4, x > 3
Compute the following function value. f(−6)

Answer 1

to find f(-6) just plug in -6 for each value x, then solve.

Answer 2

okay but i get 3 different answers..

Answer 3

LOL, wow. Sorry about that. the value of x is less than or equal to -3, so you apply it to the first equation.

\[f(x) = (-6) + 4\]

Answer 4

its -2

Answer 5

yep. :)
