The graph of a function f is given. Use the graph to answer the question.Is f(40) positive or negative?

The graph of a function f is shown below.Find f0.

Select the correct answer.Which interval describes where the graph of the function is positive?

The graph of a function f is given. Use the graph to answer the question.What is the y-intercept?

Select the correct answer.What is the range of the function shown on the graph above?

Sketch the graph of f by hand and use your sketch to find the absolute maximum and minimum values of f. (If an answer does not exist, enter DNE.)f(x) = 1 − x      if 0 ≤ x < 44x − 16 if 4 ≤ x ≤ 8absolute maximum     absolute minimum
