The value -2 is a lower bound for the zeros of the function shown below. f(x)=4x^3-12x^2-x+15 a)true b)false

  a) true

Step-by-step explanation:

The bottom-line numbers from synthetic division alternate signs, indicating that -2 is a lower bound. The given statement is true.

__

If the signs were all positive, it would indicate the proposed zero is an upper bound.

__

A graph shows all real zeros are greater than -2.

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
