Answer from: Carloslogrono10

Step-by-step explanation:

To find the zeros of this polynomial, set the polynomial equal to zero, and then set each of the factors equal to zero separately. Solve each equation for x:

x - 1 = 0 yields x = 1. The x-intercept is (1, 0).

x + 3 = 0 yields x = -3. The x-intercept is (-3, 0).

2x + 1 = 0 yields x = -1/2 The x-intercept is (-1/2, 0)

Answer from: brianna4455

(- 3, 0), (- 1/2, 0), (1, 0)

Step-by-step explanation:

p(x)=(x-1)(x+3)(2x+1)

Plug p(x) = 0

Therefore,

(x-1)(x+3)(2x+1) = 0

x - 1 = 0 or x + 3 = 0 or 2x + 1 = 0

x = 1 or x = - 3 or x = - 1/2

Hence, (- 3, 0), (- 1/2, 0), (1, 0) are zeroes of the given polynomial

Answer from: Quest

step-by-step explanation:

a. since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since 2010 0 1 2 3 4 5

profits made in 1000's 39 84 111 120 111 84

we find that profit gradually increases form 2010 to 2013 upto 120, then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a. since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.
