Question 4

metals can be used as wire because they are

a)alloys

b)ductile

c)metallic

d)shiny

Answer:   B)ductile

Most of the metals has property called ductility, this property helps the material to drawn into wires.

Explanation:

Ductility is the property of material which helps to drawn into wires. These ductile materials are not broken when the metal is hammered instead these stretch into wires.

The ductility of the metal varies by changing the alloy constituents. If the carbon content is increased in the metal ductility of the metal decreases.

Some of the metals which has ductility property are gold, copper, silver, erbium and more others.

Domain:

Range:

Step-by-step explanation:

The domain is the set of real values which can be inputted into a function and produce a real output. In this case, the domain is the following: , because this is the set of real values for which the function will produce a real output.

The range is the set of real values which a function outputs when a value from the domain is entered into the function. This is the set of y-values that one can see on the graph, the possible y-values are in between (-3) and (6).
