4. Sketch the graph of this function:
f(x) = –1 (x + 1)2 (x – 3)
Your graph must have accurately drawn xand y-intercepts and the correct overall
shape.
5. For the graph shown below write a function formula. Show any needed work. Circle your
answers.
6. Convert this quadratic function to vertex form. f(x) = 3x 2 -12x + 23

7. A football is kicked into the air. After x seconds, the football’s height in feet is given by
f(x) = –16(x – 2)2 + 64.
a. What is the greatest height reached by the football?
b. Solve the equation f(x) = 48. Explain the meaning of the answer in terms of the football.
c. What are the x-intercepts of the graph of f(x) ? Show or explain how you get your answer.
d. Sketch a graph of f(x) on the given axes.
Label the x-intercept(s), y-intercept, and vertex
with their (x, y) coordinates.
e. What is the domain of f(x)? In other words, what x-values make sense as inputs in this
problem situation?
