Answer:
The domain of a function is the set of all possible inputs for the function.
Using the table provided, the set of all possible inputs is the interval [-6 ; 4].
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values.
Using the table provided, the range is estimated on the interval [-10;20]
The y-intercept is the value on the Y-axis where the function crosses the Y-axis.
Using the table provided, the function crosses the Y-axis for f(0)=18 so for the value y = 18 in the table.
The x-intercept is the value on the X-axis where the function crosses the X-axis.
It happens twice, for f(-6)=0 and f(3)=0.
We estimate the Maximum to be 20, and the Minimum -10.
The function is positive over the interval [-6, 3], and negative over (3;4]
The function is decreasing approximately at f(-1)=20 so at the estimated interval (-1;4]
