1. Given the function f defined by f(x) = x^3-x^2-4X+4
a. Find the zeros of f
b. Write an equation of the line tangent to the graph of f at x = -1
c. The point (a, b) is on the graph of f and the line tangent to the graph at (a, b) passes through the point (0, -8) which is not on the graph of f. Find the values of a and b.
Find all the zeros of the function. When there is an extended list of possible rational zeros, use a graphing utility to graph the function in order to discard any rational zeros that are obviously not zeros of the function.
I just wanted to double check that I am correct. 1.Find the zeros for the function: f(x)= 4(x-3)(x+2)(x-4)^2 Zeros are: 3,-2, 4(multiplicity 2) 2.Find the zeros for the function: f(x)= x^3-9x Zeros are: 0, 3, -3
For the following function f(x)=2x^4-6x^2+2x-1. Find the maximum number of real zeros and Use Descartes's rule of signs to determine how many positive and how many negative zeros the function has. You do not need to find the
Using the rational zeros theorem to find all zeros of a polynomial The function below has at least one rational zero. Use this fact to find all zeros of the function h(x)=7x^4-9x^3-41x^2+13x+6 if more than one zero, separate with
The function f(x)=x^2+5x+6 has zeros at -2 and -3. What are the zeros of the function y=-2f(x/11) ? Do you just plug x/11 into each x value in f(x)? Like f(x)= (x/11)^2+5(x/11)+6 (I exclueded the -2 because if I divide 0 by -2,
(a) Show that if A is an m x n matrix and A(BA) is defined, then B is an n x m matrix. (b) Show that if A has a row of zeros and B is any matrix for which AB is defined, then AB also has a row of zeros. (c) Find a similar result
f(x)=x^6+4x^5+4x^4+3x^3-x^2-5x+4 Find the maximum number of real zeros, and Use Descartes's rule of signs to determine how many positive and how many negative zeros the function has. You do not need to find the zeros.
Use the rational zeros theorem to find all the real zeros of the polynomial function. Use the zeros to factor f over the real numbers. f(x)=25x^4+26x^3+126x^2+130x+5 Find the real zeros x= Use the real zeros to factor f f(x)=
