look at the function and answer the questions.

What is x when f(x)=2 ?
What is a zero of this function?
To determine the answers to these questions, we need to understand the function given and find the corresponding values.
The given function relates the variables x and y. We have a table with pairs of x and y values:
x y
-3 2
-1 0
0 5
1 2
2 7
Now, let's answer the questions one by one:
1. What is x when f(x) = 2?
To find the value of x when f(x) = 2, we need to look for a corresponding y value of 2 in the table. We can see that when x = -3, the corresponding y value is 2. Therefore, the answer is x = -3.
2. What is a zero of this function?
In mathematics, a zero of a function is the value of x for which the function f(x) equals zero. To find the zero of this function, we need to find the x value when y = 0. Looking at the table, we can see that when x = -1, the corresponding y value is 0. Therefore, the answer is x = -1.
So, the answers are:
1. x = -3 when f(x) = 2.
2. x = -1 is a zero of this function.
