The graph of an absolute value function opens up and has a vertex of (0, -3). the domain of the function is . the range of the function is .

The domain: all real numbers;

The range:  

Step-by-step explanation:

The graph of the function y=|x| opens up and has a vertex at (0,0). If the graph of an absolute value function opens up and has a vertex of (0, -3), then the function has an expression

y=|x|-3 (see attached diagram).

The domain of the parent function y=|x| is the set of all real numbers, then the domain of the function y=|x|-3 is the set of all real numbers too.

The range of the parent function y=|x| is then the range of the function y=|x|-3 is

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
