Quiz about Finding Domain and Range of Functions

Question 1

Identify the range of the function from the given graph.

Accepted Answer

Range of the function from the given graph can be determined by observing the y-values of the highest and lowest points on the graph.

Answer

Range of the function is determined by the x-values of the highest and lowest points on the graph.

Answer

Range of the function is determined by the average of all the y-values on the graph.

Answer

Range of the function is determined by the slope of the graph.

Question 5

In finding the domain of the rational function $$r\left(x\right)=\frac{p\left(x\right)}{q\left(x\right)}$$ where p(x) and q(x) are polynomial functions, all real numbers are allowed for x except . . .
(Check all that applies.)

Accepted Answer

The ones that would make the denominator zero. $$q\left(x\right)=0$$

Accepted Answer

The ones that would make the function undefined.

Answer

The ones that would make the numerator zero. $$p\left(x\right)=0$$

Answer

The ones that would make the function zero. $$r\left(x\right)=0$$
