Each product \(a_ix^i\) is a term of a polynomial function. The term containing the highest power of the variable is called the leading term. We can see these intercepts on the graph of the function shown in Figure \(\PageIndex{11}\). The leading term is \(3x^4\); therefore, the degree of the polynomial is 4. It is possible to have more than one \(x\)-intercept. Given two points on the curve of an exponential function, use a graphing calculator to find the equation. The \(x\)-intercepts are found by determining the zeros of the function. However, 2^2 (2^3)^3=2048, so these two are clearly not the same. Some examples of such equations are 2(x + 1) + 3(x 1) = 5 , (2x + 1)2 (x 1)2 = x and 22x+1 + 334x = 1 . Any lowercase letter may be used as a variable. The leading term is the term containing that degree, \(5t^5\). \Rightarrow -ln(32) = -5ln(a) To avoid ambiguous queries, make sure to use parentheses where necessary. We can combine this with the formula for the area A of a circle. To improve your math performance, practice regularly and persistently. The first two functions are examples of polynomial functions because they can be written in the form of Equation \ref{poly}, where the powers are non-negative integers and the coefficients are real numbers.
