Why is it better to have the quadratic function in vertex form instead of standard form?
If you want to graph the function, it is quite easy: y=a(x-h)2-k . . . you can plot the vertex (h,k); the 'a' tells you how wide or narrow the u-shape is, and whether it opens up or down.
What makes a function have a graph that is quadratic?
That the function is a quadratic expression.
What determines whether the graph of the quadratic function will open upward or downward?
The slope of your quadratic equation in general form or standard form.
What is the standard form of a quadratic function?
ax2 +bx + c = 0
What is the parent function for a quadratic function?
y = x2 is the parent function, but it can be in the form y = ax2 + bx + c
What different information do you get from vertex form and quadratic equation in standard form?
The graph of a quadratic function is always a parabola. If you put the equation (or function) into vertex form, you can read off the coordinates of the vertex, and you know the shape and orientation (up/down) of the parabola.
What is the equation for vertex form?
The vertex form for a quadratic equation is y=a(x-h)^2+k.
How do you convert vertex form to quadratic form?
Do you have a specific vertex fraction? vertex = -b/2a wuadratic = ax^ + bx + c
In the vertex form of a quadratic function y equals a the quantity of x-b squared plus c what does the b tell you about the graph?
The standard form of the quadratic function in (x - b)2 + c, has a vertex of (b, c). Thus, b is the units shifted to the right of the y-axis, and c is the units shifted above the x-axis.

Definition of quadratic function?
A quadratic function is a function that can be expressed in the form f(x) = ax^2 + bx + c, where a, b, and c are constants and a is not equal to 0. This function represents a parabolic shape when graphed.
What part of speech is quadratic function?
A quadratic function is a noun. The plural form would be quadratic functions.
What part of speech is function?
A quadratic function is a noun. The plural form would be quadratic functions.
What is the formula for quadratic equation in vertex form?
y=2(x-3)+1
What form of a quadratic function would be graphed having the vertex at the same point as the y- intercept?
The function would be in the form of ax2+c. The axis of symmetry would be the y-axis, or x = 0, because b would be zero. Likewise, the y-intercept is not important, as any value of c will still yield a vertex at the y-intercept.
What makes a function have a graph that is quadratic?
That the function is a quadratic expression.
Where is the vertex of a parabola?
when the function is in vertex form: y = a(x - h)2 + k, the point (h, k) is the vertex.
