The first relation gives two y-values for any given x-value (except x=6).
y² +x = 6 . . . . . is not a function
Answer:
y = x² - 13x + 36
Step-by-step explanation:
Given the zeros x = 4 and x = 9, then the corresponding factors are
(x - 4) and (x - 9)
The polynomial is then the product of the factors
y = (x - 4)(x - 9) ← expand using FOIL
y = x² - 13x + 36
Yes indeed it is. Your correct
