Question

B(x)=[x+4], what is b(-10)?

Answer 1

You have the following function:

b(x) = |x + 4|

where the bars mean absolute value. Take into account that the absolute value of any positive or negative number is equal to a positive number.

Then, by replacing b=-10, you have:

b(-10) = |-10 + 4| = |-6| = 6

Hence, b(-10) is equal to 6
