Vera claimed the solution set on the number line represents the inequality Negative 78.9999 greater-than-or-equal-to x. A number line going from negative 82 to negative 78. A closed circle is at negative 79. Everything to the left of the circle is shaded. Which error did Vera make? Vera wrote the inequality with the variable on the left side of the relation symbol. Vera wrote a relation symbol that does not represent the direction of the ray. Vera selected an inequality that does not include –79 in its solution set. Vera used the wrong number in her inequality.

Vera used the wrong number in her inequality.

Step-by-step explanation:

Inequalities are graphed to present a clearer picture of their behavior

To graph an inequality, the following are required steps

(1) Locate the indicated number on the other side of the  inequality sign variable x in the inequality equation (in this case we have 78.9999 ≥ x)

(2) Draw a number line and place an open or shaded circle around around the number specified in the inequality equation depending on whether the variable is also equal to the number

(3) Shade the possible numbers of the variable

In this case Vera used 78.999 in the equation and 79 on the graph

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
