Question

K here’s another one please help

Answer 1

Both the relations are functions, the correct answer is a.

Explanation:

In order to solve this problem we will first find the inverse relation as shown below:

`y = 3x^2 + 5\\x = 3y^2 + 5\\3y^2 = x - 5\\y^2 = (x - 5)/(3)\\y = \sqrt{(x - 5)/(3)} = (√(x - 5))/(√(3))\\y = (√(x - 5)√(3))/(√(3)√(3)) = (√(3x - 15))/(3)`

Functions are relations between two groups of numbers, for which the input must generate only one output. Using this definition we can classify both the relation and its inverse as a function, therefore the correct answer is a.
