Domain is the numbers you can use
range is the result of inputing the domain

an interesting fact is that the inverse of a function switches the domain and range

basically
the domain of f(x) becomes the range of f^-1(x)
the range of f(x) becomes the domain of f^-1(x)
so just find the domain and range of f(x)

$f(x)=3x- \frac{1}{2}$
there are no restrictions
all real numbers can be used
all real numbers can result

so the answer is domain and range for both is all real numbers

Terry and Bob each have an aquarium. Terry’s aquarium is 14 cm long, 12 cm high, and 10 cm wide. Bob’s aquarium is 13 cm long, 1

MArishka [77]

Find the volume of each tank by multiplying the length by the width by the height:

Terry: 14 x 12 x 10 = 1680 cubic cm.

Bob: 13 x 15 x 8 = 1560 cubic cm

Terry’s aquarium is larger and can hold more water.
