Aquadratic equation is shown below:

3x2 − 16x + 2 = 0

part a: describe the solution(s) to the equation by just determining the radicand. show your work.

part b: solve 9x2 + 3x − 2 = 0 by using an appropriate method. show the steps of your work, and explain why you chose the method used.

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=
