Answer:
f(x) = x³ + x² - 5x + 3
Step-by-step explanation:
The cubic polynomial has zeros at 1, 1, - 3.
Therefore, x = 1, 1, - 3 are the roots of the polynomial and hence, (x - 1), (x - 1) and (x + 3) will be factors of the cubic polynomial.
Hence, we can write the polynomial as a function of x as
f(x) = (x - 1)(x - 1)(x + 3)
⇒ f(x) = (x² - 2x + 1)(x + 3)
⇒ f(x) = x³ - 2x² + 3x² + x - 6x + 3
⇒ f(x) = x³ + x² - 5x + 3
So, this is the cubic polynomial function in standard form. (Answer)

Answer:
$0.22
Step-by-step explanation:
Ellen has a coupon of 1.55 off a loaf of bread
The regular price of the bread is 4.63, the loaf is cut into 14 slices
Therefore if she uses her coupon the price per slice can be calculated as follows
= 4.63-1.55
= 3.08
3.08/14
= 0.22
Hence the price is $0.22
