Sketch the graph of the function y = 3x^2 – 30x + 5.
What are the domain and range of the function?
What are the x-intercepts? Approximate to two decimal places.
a. domain = [–70, ∞); range = (–∞, ∞);
x-intercepts: points (9.97, 0) and (0.10, 0)
b. domain = (–∞, ∞); range = [–70, ∞);
x-intercepts: none
c. domain = [–70, ∞); range = (–∞, ∞);
x-intercepts: points (9.83, 0) and (0.17, 0)
d. domain = (–∞, ∞); range = [–70, ∞);
x-intercepts: points (9.83, 0) and (0.17, 0)
