Question

Given b(x)= |x+4|, what is b(-10)?
-10
-6
6
14

Answer 1

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.
