Given b (x) = |x+4|, what is b (-10) ?

-10

-6

6

14

The function is b (x) = |x+4|,

which means that b (-10) = |-10+4|, since we can replace both x-es above with any number. (This is what the rule means.)

Further, |-10+4|=|-6|. We know that the absolute value gives us always positive values, so |-6|=6.

Thus, the answer is 6.
