Which of the following is the domain of the function based on the input-output table below?
​

Don't know g g g g f sda g afg ae rg ad v

Step-by-step explanation:

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
