1. If f(x) = |x| + 9 and g(x) = –6, which describes the value of (f + g)(x)?
2. If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (c*d)(x)?

(f + g) (x)   = f(x) + g(x)   =  [xl + 9  - 6   =   lxl + 3

 


2. If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (c*d)(x)?

 

(c*d)(x)  =  c(x)*d(x)   =   [ 4x - 2] * [x^2 + 5x ] =  4x^3 + 20x^2 - 2x^2 - 10x  =

 

4x^3 + 18x^2 - 10x

 

 

 

 

cool cool cool
