This lesson has two major parts, easy and advanced. Whenever you need to draw a graph, you always need to follow the following guidelines. How to plot a nice graph with sweaty shaky hands Determine what kind of function you are going to plot linear, quadratic, absolute value, etc, and act accordingly The remaining chapters are advanced.

Question 366613: a punter, punts the football at the 40 yard line at the equation of y=-0.008x^2+2.5x+1. I know how to graph a linear function starting at a cirtain point, how would you graph a quadratic function from the 40 yard line? Answer by edjones (8007) (Show Source):
How to complete the square to find the minimum/maximum of a quadratic function Assume that you are given a quadratic function of a general form y = . You know that the plot of this function is a parabola. You also know that if the coefficient "a" at is positive, then the parabola has a minimum and the parabola is opened upward.
Question 585845: how to determine whether the equation defines y as a function of x. is it a function yes or no to the problem: x=y^2-6 and problem y=x^2+6 Found 2 solutions by KMST, chimm:
You can put this solution on YOUR website! How can I tell if a graph opens up or down by looking at the equation For the quadratic equation: if a>0 it will open up. if a<0 it will open down. Let's look at an example: for a=2, b=2 and c=1 for a=-2, b=2 and c=1 I hope the above steps were helpful.
You can put this solution on YOUR website! a function is defined as an equation where every value of x has one and only one value of y. y = x^2 would be a function. the graph would look like this: the graph of y = +/- sqrt (x) would be a relation because each value of x can have more than one value of y. this occurs everywhere except at the vertex of the graph. that graph looks like this: you ...
Question 254213: Explain how you know if the graph of a quadratic is wider or narrower than the standard quadratic, y=x^2. Answer by Edwin McCravy (20055) (Show Source):
You can put this solution on YOUR website! X-intercepts are where a a graph intersects the x-axis. In other words, x-intercepts are x-values which make the function value 0. So to find x-intercepts we need to find the x-value (s) where f (x) = 0. So finding the x-intercepts of your function means solving: Factoring this we get: The only way for a product to be zero is if one of the factors is ...
You can put this solution on YOUR website! your graph would look like this: when x is less than -1, you have a line at y = 3 extending from minus infinity to -1 but not existing at x = -1. that's the reason for the empty center dot at x = -1. it says that the line extends to -1 but is not present at x = -1. when x is equal to -1, you have a solid center dot at y = 2. there is no line attached ...
