Question

Find the range of the function

Answer 1

c. (-∞, 10]

Explanation:

A function
`f` from a set
`A` to a set
`B` is a relation that assigns to each element
`x` in the set
`A` exactly one element
`y` in the set
`B`. The set
`A` is the domain (also called the set of inputs) of the function and the set
`B` contains the range (also called the set of outputs). From the figure below, we can see that this function is a parabola that opens downward and whose vertex is
`(0, 10)`. Therefore, the range of this function is (-∞, 10]
