Functions of Zeros

Find all zeros. One zero has been given.
f(x) = x⁴ + 8x³ + 14x² - 8x - 15; x = -5

• -2,1,-1,-5
• -3,1,-1,-5
• 3,-3,4,0
• -1,1-5,3

If the binomial (x - 7) is a factor of the polynomial function f(x), which statement must be true?

• f(7) = -7
• f(7) = 0
• f(-7) = 0
• f(-7) = -7

Factor f(x)= x³ - 2x²-13x - 10  given that (x - 5) is one factor.

• (x- 5)(x - 1)(x - 2)
• (x - 5)(x + 2)(x - 2)
• (x - 5)(x + 2) (x + 1)
• (x - 5)(2x - 13)

Factor:
 x³-12x²+47x-60=0 when 5 is a root.

• (x-3)(x-4)(x-5)=0
• (x+1)(x-4)(x-5)=0
• (x-3)(x-4)(2x-5)=0
• (x-5)(x-4)(x-5)=0

f(x)=(x+4)(x-3)(x-2)

List the zeros for this function.

• x = -4, x = 3, x = -2

• x = -4, x = 3, x = 2

• x = -4, x = -3, x = 2

• x = 4, x = 3, x = 2

Use the graph of f(x) to determine the real solutions to f(x)=0.

• -10

• 2, 5

• 0, 7

• no real solution
