b) {-6,-3,-2,0,3}

c) {-3,0,2,3,6}

d) {-4,-1,1,2,7}

Answer 1

What is the DOMAIN of the INVERSE function? { (3,4), (-2,1), (-6,-7), (-3,-2), (0,-1) }

What is inverse function:

Let's suppose f and g are inverse functions. That means that if f(x) = y, then by definition, g(y) = x. Therefore, the graph of f will have point (x, y) and the graph of g will have the point (y, x).

To find the inverse function Domain rewrite the ordered pair as

(4,3), (1,-2), (-7,-6), (-2,-3), (-1,0)

Domain((x values): {4, 1, -7, -2, -1}...... you can rewrite this in least to greatest

{-7, -2, -1, 1, 4}

A is the answer.
