Step-by-step explanation:
given
f(x) =3x² - x - 4
To obtain roots set f(x) = 0, that is
3x² - x - 4 = 0
To factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × - 4 = - 12 and sum = - 1
The factors are + 3 and - 4
Use these factors to split the x- term
3x² + 3x - 4x - 4 = 0 ( factor the first/second and third/fourth terms )
3x(x + 1) - 4(x + 1) = 0 ← factor out (x + 1)
(x + 1)(3x - 4) = 0
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
3x - 4 = 0 ⇒ 3x = 4 ⇒ x =
The roots are x = - 1 and x =
By the list provided that would give option 1

Step-by-step explanation:
Slope is the fraction, or ratio, of the vertical change over the horizontal change of two sets of data. In this case, the slope is the rate at which the house rises over expands:
Simplifying the fraction to simplest form gives an overall rate of 1/6 ft.
