Marta_Voda [28]

Answer:

You would need to score a 93% to have an average of 90.

Step-by-step explanation:

Well, to check my work you would need to find the average.

So, 93 + 92 + 88 + 87 = 360. Then you divide by four; 360 / 4 = 90. ^^

Graph the given relation or equation and find the domain and range. Then determine whether the relation or equation is a functio
KiRa [710]

Domain: \{3.3,-1.7,-4.7\}

Range: \{5.3,3.3,-2.7\}

The relation is not a function.

Explanation:

The coordinates (3.3,5.3), (-1.7,5.3), (-4.7,3.3), (-4.7,-2.7) are plotted in the graph. The image of the graph is attached below.

The domain of a relation is the set of all x-values for which the function is well defined. Thus, the domain are \{3.3,-1.7,-4.7\}

The range of a relation is the set of all y-values obtained by substituting the values for x in the function. Thus, the range are \{5.3,3.3,-2.7\}

The relation (3.3,5.3), (-1.7,5.3), (-4.7,3.3), (-4.7,-2.7) is not a function since, -4.7 has two different y-values. By definition of function, the function cannot have two different y-values for the same x-value.
