If f(x) = 5x – 6 and g(x) = x2 – 4x – 8, find (f + g)(x). a.(f + g)(x) = 6x2 – 4x – 14 b.(f + g)(x) = x2 – 9x – 2 c.(f + g)(x) = x2 – x – 2 d.(f + g)(x) = x2 + x – 14

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

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
