Can someone answer this? will mark what are the domain and range of the function? explain. f(x)= a. the domain is {x | x ∈ r, x ≠ 0}. the range is {f (x) | f (x) < 0}. b. the domain is {x | x ∈ r, x ≠ 0}. the range is {f (x) | f (x) ∈ r, f(x) ≠ 0}. c. the domain is {x | x ∈ r, x ≠ 0}. the range is {f (x) | f (x) > 0}.

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}.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
