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
The angle of 2 is 150 degrees
The slope-intercept form:

m - slope
b - y-intercept
We have the slope m = 4 → 
and point (1, 6). Substitute:

<em>subtract 4 from both sides</em>

<h3>Answer: y = 4x + 2</h3>
The answer is A because it is
