Find the domain and range of the following function ƒ(x) = 3|x + 7| - 2? a. domain: [-2,∞) range: (-∞,∞) b. domain: (-2,∞) range: (-8∞,∞) c. domain: (-∞,∞) range: [-2,∞) d. domain: (-∞,∞) range: (-2,∞)

D.Domain: (-∞,∞) Range: (-2,∞)

is the right answer.

Step-by-step explanation:

Given is a function as

This is an absolute value function hence the minimum value of

|x+2|=0

Hence the range cannot be below -2

For maximum no limit

Domain can be any real value

Hence option d is correct answer.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
