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

Step-by-step explanation:
You divided in the wrong order. The resulting image always goes first then the preimage is afterward.
scale factor = (new)/(old) = 10/8 = 1.25
<h3>Answer is choice B</h3>
The scale factor is larger than 1, so this means we have an enlargement going on.
