WebWhat this question means is what number is 7x-2 approach if x become extremely small. 1. If x is -1, 7x-2 is -9. 2. If x is -10, 7x-2 is -72. 3. If x is -100, 7x-2 = -702. Here's a pattern, as x become smaller and smaller, 7x-2 become smaller and smaller as well. That means when x approach negative infinity, 7x-2 approach negative infinity as well. The coefficients of a Taylor series of any rational function satisfy a linear recurrence relation, which can be found by equating the rational function to a Taylor series with indeterminate coefficients, and collecting like terms after clearing the denominator.

WebMay 23, 2024 · 1. To ensure all of the required properties, consider. f ( x) = x − 5 + p ( x) ( x − 2) ( x + 3), which has asymptotes in the right places. To get the zeros at 3 and − 2, we need f ( 3) = 0 and f ( − 2) = 0. These conditions imply p ( 3) = 12 and p ( − 2) = − 28. Let p ( x) = a x + b. Then we have 3 a + b = 12 and − 2 a + b = − 28.
