Answer:
(f+g)(x)=4x+3
Step-by-step explanation:
Given the functions f and g defined above, their sum f+g is defined by (f+g)(x)=f(x)+g(x). Using algebra, we thus have (f+g)(x)=2x-1+2x+4=4x+3.
I believe it's the 3rd one
3,5,6,
a =3
d = 5-3 = 2
Tn= a+(n-1)d
T6= 3+(6-1)2 = 3 + (5)2 = 3 + 10 = 13
If the Upper equation is 1 and the lower is 8:
