How many roots does y equals x2 - 4x plus 6 have?
No real roots. Imaginary roots as this function does not intersect the X axis.
What use the discriminant to determine the nature of the roots of x2 plus 2x plus 5 equals 0?
No real roots
How To Determine The Roots Of Quadratic Function?
x = [ -b ± √(b2-4ac) ] / 2a Using this formula you get 2 roots for + and -
Use the quadratic equation y equals x2 plus 3x plus 9 Calculate the discriminant to determine the number of real roots?
The discriminant is -27 and so there are no real roots.
How to find the roots of a function in MATLAB?
To find the roots of a function in MATLAB, you can use the "roots" function for polynomials or the "fzero" function for general functions. The "roots" function calculates the roots of a polynomial, while the "fzero" function finds the root of a general function by iteratively narrowing down the root within a specified interval.
How do you determine the values for which a rational expression is undefined?
A rational expression is not defined whenever the denominator of the expression equals zero. These will be the roots or zeros of the denominator.
How many roots does y equals -6x2 plus 3x - 4 have?
-6x2 + 3x - 4 can be factored into (-x + 4)(x + 1). This equals 0 only when x is either 4 or -1. Therefore, the latter two numbers are both roots of the given function.
What is another name for the root of a function?
The "root" of a function is also called the "zero" of a function. This is where the function equals zero. The function y=4-x2 has roots at x=2 and x=-2 The function y=4-x2 has zeroes at x=2 and x=-2 Those are equivalent statements.
How do you show an equation has 3 real roots?
To show that an equation has three real roots, you can analyze its derivative to find critical points and determine the behavior of the function. If the function is continuous and differentiable, use the Intermediate Value Theorem to confirm sign changes between critical points, indicating the presence of roots. Additionally, applying Descartes' Rule of Signs can help estimate the number of positive and negative roots. Finally, plotting the function or using numerical methods can provide visual confirmation of the three real roots.
What will happened to the roots if the tissues are damage?
the roots will not function well.
What will happen to the roots if the tissues are damaged?
