Given that f(x)=x-9,g(x) = 3x^2- 2x + 5, and h(x)=-6x, find each function.
A. (f+g)(x)
B. (h-g)(x)

hi

f(x) = x-9  ;  

g(x) = 3x²-2x +5  

h(x) = -6x  

A :  f+g =  x-9  +3x²-2x+5  

     f+g =  3x²-x-4  

b :  h-g  =  -6x - 3x²+2x-5

     h-g =    -3x²-4x-5

step-by-step explanation:

the answer is 128

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
