How do you use the important points to sketch the graph of #f(x) = 12x^2 + 2#?
1 Answer
If I were you, I'd use the y-intercept and two points on the negative and positive parts of the graphs.
Explanation:
First, I'd substitute
Then, I'd pick two easy numbers on each side to graph. For example, I'd use
Now, I'd substitute the
This coordinate will be
Then, do the same thing to find the coordinates of the other point's you've chosen.
The points that I've chosen:
Notice how the
graph{12x^2+12 [-98.5, 84.7, -0.36, 91.24]}
(you can zoom in and out on the graph)
Hope this helps!
