Which point is an x-intercept of the quadratic function
f(x) = (x + 6)(x – 3)?
(0,6)
(0,–6)
(6,0)
(–6,0)

we have

we know that

The x-intercept of the function is the value of x when the value of the function is equal to zero

so

For

the x-intercepts of the function are

therefore

the points of the x-intercept of the quadratic equation are

and

the answer is the option

c. 4 1/4 pounds

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
