-16, +2 are two nhmbers that multiply to -32 and add to -14
Answer: I encourage you to ask real questions for the sake of others.
Step-by-step explanation: (thx for points tho :))
Answer:
the discounted price by 10% is P(x) = 0.9x. the price minus a $150 coupon is C(x) = x - 150. so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!
What are the 1-4 you have numbered? but to, summarize, if you can draw a vertical line and hit more than one point anywhere on the graph its not a function, so B, and if there are any bends or curves, but still is a function, it's a non linear function, like the other two.
x³ + 8x² + 11x - 20 ← the first on list
given the roots of a polynomial, say x = a, x = b and x = c
then the factors are (x - a), (x - b) and (x - c)
the polynomial is the product of the factors
f(x) = (x - a)(x - b)(x - c)
here x = - 5, x = - 4 and x = 1, hence factors are
(x + 5), (x + 4) and (x - 1)
f(x) =(x + 5)(x + 4)(x - 1) ← expanding factors gives
f(x) = (x² + 9x + 20)(x - 1) = x³ + 8x² + 11x - 20
