Intercepts and Turning Points of Polynomials. The leading term is the term containing that degree, \(5t^5\). Identify the term containing the highest power of \(x\) to find the leading term. \Rightarrow -ln(32) = -5ln(a) We often rearrange polynomials so that the powers are descending. To ensure you are clarifying the math question correctly, re-read the question and make sure you understand what is being asked. what do you mean by optimize your notation? Because of the form of a polynomial function, we can see an infinite variety in the number of terms and the power of the variable. Write a power function y 5 axb whose graph passes through (3, 2) and (6, 9). For example: if you are asked to find out the square of 5, 5, you'll simply need to multiply 5 by itself: 5 = 5 x 5 = 25. 50 = c \cdot 5^r \\ There are many ways to improve your writing skills.
