The domain of the function shown in the graph above include the following: B. -4 ≤ x < ∞.
In Geometry, a domain is the set of all real numbers (x-values) for which a particular function is defined.
Generally speaking, the horizontal section of any graph is typically used for the representation of all domain values. Additionally, domain values are both read and written by starting from smaller numerical values to larger numerical values, which implies from the left of a graph to the right of the coordinate axis.
By critically observing the graph of the quadratic function shown above, we can reasonably and logically deduce the following domain and range:
Domain = [-4, ∞) or -4 ≤ x < ∞.
Range = [-3, ∞) or -3 ≤ x < ∞.
