Timed question which are the roots of the quadratic function f(b) = b2 – 75? select two options.

a b = 5 startroot 3 endroot
b b = negative 5 startroot 5 endroot
c b = 3 startroot 5 endroot
d b = negative 3 startroot 5 endroot
e b = 25 startroot 5 endroot

(b = 5 StartRoot 3 EndRoot)

and

(b = Negative 5 StartRoot 3 EndRoot)

Step-by-step explanation:

we have

we know that

The roots of the quadratic function are the values of x when the value of the function is equal to zero

so

For f(b)=0

Solve for b

Adds 75 both sides

take square root both sides

Simplify

therefore

(b = 5 StartRoot 3 EndRoot)

and

(b = Negative 5 StartRoot 3 EndRoot)

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
