1.suppose f(x)=6x^2+2x-7 and g(x)=4x-3.find each of the following function. a. (f+g)(x) b.(f-g)(x) 2.suppose f(x)=2x-3x and g(x)=1-2x. find each of the following functions. a. (f+g)(x) b.(f-g)(x)

(1)

(f+g)(x) = 6x^2+2x-7+4x-3=6x^2+6x-10

(f-g)(x)=6x^2+2x-7-4x+3 = 6x^2-2x-4

(2)

(f+g)(x)=2x-3x+1-2x=-3x+1

(f-g)(x)=2x-3x-1+2x=x-1

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
