in the quadratic formula ax©÷+bx+c, what does the "a" stand for in ax©÷?
I assume that ax© means a x^2.
a is a constant or "coefficient" that multiplies the x^2 term.
In the quadratic formula y=ax^2+b+x
Changing c moves it up and down.
Changing b changes the slope.
Changing a alters the curvature of the parabolic element.
The general rule is, that as the absolute value of "a",becomes greater than 1, the graph becomes steep or narrow.
Changing "c" only changes the vertical position of the graph, not it's shape.
In the quadratic formula ax^2 + bx + c, the "a" stands for the coefficient of the quadratic term. It is the numerical value that multiplies the highest power of x, which is x^2 in this case.
To determine the value of "a" in a given quadratic equation, you can examine the equation in its standard form, which is written as "ax^2 + bx + c = 0." In this form, "a" is the coefficient of x^2, "b" is the coefficient of x, and "c" is the constant term.
For example, in the quadratic equation 3x^2 + 2x - 5 = 0, the value of "a" is 3 because 3 is the coefficient of x^2.
If you have a quadratic equation written in a different form, such as vertex form or factored form, you can transform it into the standard form to identify the value of "a."
