Consider the functions f(x)=3x^2, g(x)=1/3x, and h(x)=3x. Which statements accurately compare the domain and range of the functions? Select two options. 1. All functions have a unique range.
2. The range of all three functions is all real numbers.
3. The domain of all three functions is all real numbers.
4. The range of f(x) and h(x) is all real numbers, but the range of g(x) is all real numbers except 0.
5. The domain of f(x) and h(x) is all real numbers, but the domain of g(x) is all real numbers except 0.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

the answer is  

a.
