Question

Identify the zeros of the polynomial function N(x)=1/2 (x-1)(x+3).

Answer 1

Answer:

a:x=-3

c:x=1

Step-by-step explanation:

The zeros of a function are the values of x for which the value of the function f(x) becomes zero.

In this problem, we have the following function:

$f(x)=\frac{1}{2}(x-1)(x+3)$

Here we want to find the zeros of the function, i.e. the values of x for which

$f(x)=0$

In order to make f(x) equal to zero, either one of the factors $(x-1)$ or $(x+3)$ must be equal to zero.

Therefore, the two zeros can be found by requiring that:

1)

$x-1=0\\\rightarrow x=+1$

2)

$x+3=0\\\rightarrow x=-3$

So the correct options are

a:x=-3

c:x=1
