Respuesta :
domain: x ≥ -1; range: y ≥ -2; y-intercept: (4,0); x-intercept: (0,8)
How do you find the domain of a function?
Let y = f(x) be a function with an independent variable x and a dependent variable y. If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that chosen x-value is said to belong to the domain of f.
How do you identify the domain and range of a function?
To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).
