Question

Use the graph of the function y= g(x) below to answer the question

Answer 1

We have the next graph

(a) To know if g(-1) is negative we must see the graph when x = 0

We can see that when x = 0 the function takes the value of -4. Since -4 is negative, g(-1) is negative.

So, the answer to the question is: Yes

(b) To know for which values of x g(x) = 0, we must see the points where the function passes through the x-axis.

In this case we can see only one point: (1, 0)

So, the answer is

`1`

(c) To find the values of x where g(x) < 0 we must see the part in the graph that is below the x-axis.

In this case, these values go from

`\lbrack-3,1)`
