Which are the roots of the quadratic function f(b) = b2 – 75? check all that apply.

The roots of the given quadratic function is and  

Step-by-step explanation:

   Given: Quadratic function

We have to find the roots of the given quadratic function

Since, roots of the quadratic equation is the points where the value of function is zero.

That is f(x) = 0

Consider the given function  

Put f(b) = 0

Simplify , we have,

Taking square root both side, we have,

Simplify we have,

Thus, The roots of the given quadratic function is and
