What is an expression that has a value of 35 when p=7

The function g(x) is defined as shown. x-1, -2 g(x) = 2x+3, -1 6-x, x23

Write a corresponding real world problem to represent 2x - 125=400

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0
