To determine which of the statement is/are true, we simply have to evaluate the given choices.
a. f(x) = 0 when x = -1
f(x) = (-1)^3 - (-1)^2 - 4(-1) + 4
f(x) = 6
FALSE
b. f(x) divided by x - 1 has a remainder of 0.
f(x) = (1)^3 - (1)^2 - 4(1) + 4
f(x) = 1 - 1 - 4 + 4 = 0
TRUE.
c. (x - 1) is a factor of f(x)
Since, the division of f(x) by x - 1 gave an answer of zero this means that it is a factor.
TRUE.
d. f(-1) = 0.
In relation to letter a of this item, if we are to substitute -1 to x of the given equation, the answer is 6 instead of zero.
Answer:
2
Step-by-step explanation:
Answer: Symmetric Property
Explanation: The symmetric property states that x = y, then y = x.
So the symmetric property allows us to
switch the left and right sides of an equation.
