(2.10) Radical Functions and Rational Exponents Unit Test Part 1- Test (1-14) 13. How can you tell if radicals are like radicals? (2 points)
Like radicals have a similar root (square root, cubed root, and so on.) and a similar articulation under the extreme sign (or numbers whose force is the equivalent). So as to decide whether two radicals resemble, streamline both and afterward check both the root and the articulation under the extreme sign. For me it was OMIT. 2/2 points
End of (2.10) Radical Functions and Rational Exponents Unit Test Part 1- Test (1-14) 14. Is the inverse of a function always a function? Explain. (2 points)
No, the inverse of a function is not always a function cause a function cannot have two different outputs for one or more input. And if the original function has two or more inputs that result in a same output, when you inverse the original function, the outputs of the original are the inputs of the inverse function and the inputs of the original are the outputs of the inverse. That implies that the inverse function would have some inputs related with more than one output, which is the negation of a function. For me it was OMIT. 2/2 points The final score is 18/18 (100%). (That is if you put those answers.)

(2.10) Radical Functions and Rational Exponents Unit Test Part 1- Test (1-14) 11. Describe the relationship of input and output values for composite functions. (2 points)
The composition of the functions f(x) and g(x) is defined as (f∘g)(x)=f(g(x)). (f∘g)(x)=f(g(x))means that the output of the function g(x) is the input of the function f(x). For me it was OMIT. 2/2 points
