For each graph state the domain and range.

Try this option:

a) domain: x∈(-∞;+∞); range: y∈(0;+∞);

b) domain: x∈(-∞;+∞); range: y∈(-∞;5].

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
