## How do you enter a square root in WeBWorK?

For square roots, you can use sqrt() or the exponent (1/2). For example, the square root of two in WeBWorK is either sqrt(2) or 2^(1/2). For cube roots, use the exponent (1/3). The cube root of 7 is then 7^(1/3).

## How do you write domain in WeBWorK?

What is the domain of ? One answer is x>=0 (x is greater than or equal to 0). The best way to enter this in WeBWorK is by using interval notation: [0,infinity).

## How are intervals written?

Intervals are written with rectangular brackets or parentheses, and two numbers delimited with a comma. The two numbers are called the endpoints of the interval. The number on the left denotes the least element or lower bound. The number on the right denotes the greatest element or upper bound.

## How do you write multiple intervals?

Using Interval NotationIf an endpoint is included, then use [ or ]. For infinite intervals, use Inf for ∞ (infinity) and/or -Inf for -∞ (-Infinity). If the set includes more than one interval, they are joined using the union symbol U.

## How do you express a domain?

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

## How do you tell if a graph is a function?

To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.

## How do you tell if a relation is a function?

How To: Given a relationship between two quantities, determine whether the relationship is a function.Identify the input values.Identify the output values.If each input value leads to only one output value, classify the relationship as a function.

## How can you tell if something’s a function?

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

## How do you know if a function is one to one without graphing?

If the graph of a function f is known, it is easy to determine if the function is 1 -to- 1 . Use the Horizontal Line Test. If no horizontal line intersects the graph of the function f in more than one point, then the function is 1 -to- 1 .
