We looked at the height of Hannah's toy rocket with respect to time at the beginning of this section and saw that it reached a maximum height of \(64\) feet after \(2\) seconds. The slope-intercept form is y = m x + b y = m x + b, where m m is the slope and b b is the y-intercept.

So your answer would be (1,0). Using graph paper is the best way. Open downward, same symetry axis, same, x-coordinate of the vertex.

Let’s graph y=2x 2-x (red) and y=2x 2-4x (blue):. Consider the vertex form of a parabola. We can apply the "elimination method" by simply adding both equations together.

By elimination, you would need to put theses equations in to standard form y = 2x - 2 ---- move the 2x to the other side-2x + y = -2 ---- this next step isnt neccesary, but i like to do it. Rewrite the equation in vertex form. Refer to the explanation.

Tap for more steps. Now, we see that our hypothesis is not completely correct, for – b /2 for the first graph would give us ½, but we have ¼. So change it to y= -2x+2.

−2x = y2 - 2 x = y 2. If you really did mean `y<2x^2+4x-3`, the graph is the same, but with a dotted line instead of a solid one, and then shaded below the parabola. Divide each term in − 2 x = y 2 - 2 x = y 2 by − 2 - 2.

"M" is your slope and "B" is your y-intercept. The idea is get rid of one of the variables. Next, we note that as the value of a increases, the parabola gets narrower with respect to the x-axis.

Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the latexx/latex-axis. Using those graphs, compare and contrast the shape and position of the graphs. We first note that when a is a negative value, the graph is reflected across the x-axis and the vertex becomes the maximum point.
