Answer:
C. The domain is {x | x ∈ R, x ≠ 0}. The range is {f (x) | f (x) > 0}.
Step-by-step explanation:
f(x)= 3/ (5x^2)
the domain is the possible x values
the only values x cannot take is 0 (we cannot divide by 0)
The domain is {x | x ∈ R, x ≠ 0}
the range is the possible y values
y cannot be negative since x is squared
and cannot be 0 since x^2 cannot equal 0
The range is {f (x) | f (x) > 0}.
