Answer:
- The Range is the set of all outputs for a function
- The Domain is the set of all inputs for a function
For example
Here Domain and range both are set of all real numbers
A rate is a ratio of two quantities: miles per hour, calories per cookie,dollars per person, ... a unit rate just specifies the units (miles, hours) of<span> the two quantities.</span>
(x)(3x - 5) = 12
3x^2 - 5x = 12
3x^2 - 5x - 12 = 0
(x - 3)(3x + 4) = 0
x = 3, -4/3
The answer must be negative so the number is -4/3.
Hope this helps!
