Question

I GIVE MEDALS

Decide whether the given x value is a zero of the function.

f(x) = x3 + 5x2 + x + 5; x = –5

Select one:
a. No, because there is more than one zero.
b. No, because substituting the value does/does not make the function equal to zero.
c. Yes, because substituting the value does/does not make the function equal to zero.
d. none of the above

Answer 1

?

Answer 2

oh sorey..its B..its not zero..

Answer 3

i missed it up...

Answer 4

™Maybe B

Answer 5

To find the zeros of a function, first, factor the polynomial, which would be (x^2 + 1)(x + 5), or (x - 1)(x + 1)(x + 5), then set each binomial equal to zero and solve, to get x = 1, x = -1, and x = -5 for the zeros.

Answer 6

No, because substituting the value does/does not make the function equal to zero.

Answer 7

It would be A I think, because there is more than one zero.

Answer 8

The zeros would be x = -5, x = 1i, and x = -1i
