Which are the roots of the quadratic function f(b) = b2 – 75? select two options. b = 5 startroot 3 endroot b = negative 5 startroot 5 endroot b = 3 startroot 5 endroot b = negative 3 startroot 5 endroot b = 25 startroot 5 endroot

b = 5 StartRoot 3 EndRoot

b = Negative 5 StartRoot 3 EndRoot

Step-by-step explanation:

we have

Remember that the root of a function is the value of x when the value of the function is equal to zero

In this problem

The roots are the values of b when the function f(b) is equal to zero

so

For f(b)=0

square root both sides

Simplify

 and

therefore

b = 5 StartRoot 3 EndRoot

b = Negative 5 StartRoot 3 EndRoot
