  x = {-9, -4, -3/2}

Step-by-step explanation:

The zeros are the values of x that make the factors zero. (If a factor is zero, the product will be zero.)

x+4 = 0

  x = -4 . . . . subtract 4

2x+3 = 0

  2x = -3 . . . . subtract 3

  x = -3/2 . . .  divide by 2

-x-9 = 0

  -9 = x . . . . add x

The zeros are ...

  x = {-9, -4, -3/2}

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
