Question

Find the range of the function

Answer 1

Answer:

c. (-∞, 10]

Step-by-step 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]
