Two of the factors are easy to find. If I have zeroes at x = −1 and x = 4, then I must have factors of x − (−1) = x + 1 and x − 4. The other solution is messy, what with the square root in it. Since they specified that the polynomial has rational (that is...
Find the horizontal asymptote of the following function: y=x+2x2+1\small{ \boldsymbol{\color{green}{y = \dfrac{x + 2}{x^2 + 1} }}}y=x2+1x+2 First, notice that the denominator is a sum of squares, so it doesn't factor and has no real zeroes. In other words, this ...
Chapter 3/ Lesson 2 95K The additive inverse is a specific number, and every real number has one! That is, these inverses occur in pairs. We'll look at what their properties are, how to find them, and the most common applications. ...
Use the same procedure. Once you get used to synthetic division, you will find it very fast. You will use it to factor polynomials in order to find their "zeroes," which will be the x-intercepts on the graph. Upvote • 0 Downvote Add comment ...
