Answer:

Step-by-step explanation:

y = mx + b

m = Δy/Δx = (-1 - (-7)) / (-3 - 6) = 6/-9 = -2/3

y = (-2/3)x + b

-1 = (-2/3)(-3) + b

-1 = 2 + b

b = -3

y = (-2/3)x - 3

What is a quadratic polynomial function with zeros 3 and -3?

Lemur [1.5K]

Answer:

f(x) = x² - 9

Step-by-step explanation:

Given x = a is a zero of the polynomial f(x) then (x - a) is a factor

Given zeros are x = 3 and x = - 3, then corresponding factors are

(x - 3) and (x - (- 3) ), that is

(x - 3) and (x + 3)

The function is then the product of the factors, that is

f(x) = (x - 3)(x + 3) ← expand using FOIL

f(x) = x² - 9
