Find the range of the function y = 7x - 1 when the domain is {-1, 0 1}

Range: {-8;-1;6}

Step-by-step explanation:

The domain of a function is the set of all the values for which the function is defined (x-axis).

The range of a function is the set of all the values that f takes (Y-axis).

To calculate the range we must observe what value the function takes when entering the values for which it is defined (the domain).

In this case, those values are:

{-1,0,1}

Range: {-8;-1;6}

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
