What is the domain and range of h of x equals absolute value of x plus 3?
domain is what x values you are allowed to put into an equation.In this case there is no restrictions. x= all real numbers.range is the output once you put these numbers in the equation.h(x)=>all real numbers > 0 because the absolute value can not be negative.
What does x - y?
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
How do you know what the inputs and outputs are in functions?
if you have the equation, choose one of the pairs and put one of them in the position of x and solve. if you get the leftover value, the one you put in the equation is the x, independant variable, the other is y
What two numbers can you multiply to get -3?
Let one of the numbers be x and other be y. According to question: xy = -3 Put any value of x then value of y = -3/x. Let us say x = 1 then y = -3/1 = -3. And if x = 3 then y = -3/3 = -1. So for any value of x(except 0) we get a value of y. So there are infinitely many solutions of the given equation.
What happens to the x-value of the ordered pair when the ordered pair is reflected over the x-value?
If the reflection is over the x value, the x-value does not change.
