2. Reading Graphs A graph of a function is shown. Using the graph, find the indicated function values; that is, given the input, find the output. Rewrite the information above as ordered pairs.

4. Zeros of Functions The values of for which are called the zeros of the function. Zeros are places where the function value is zero. Places where the y value is zero. Zeros are the x values of the x-intercept.

5. Zeros of Functions (a)Find the x-intercepts of the graph of f(x). (b)Find the zeros of f(x).

6. Reading Graphs (a)Find g(-3). (b)Find g(5). (c)Find g(6). (d)Is g(-5) positive or negative? (e)For what numbers x is g(x) = 0?

7. Reading Graphs (h) What are the x-intercepts? (i)What is the y-intercept? (j)For what numbers x is g(x)= -2? (k)For what number x is g(x) = 3? (l)What are the zeros of g? (f) What is the domain of g? (g) What is the range of g?
