For the given functions f and g, complete parts (a)-(h). For parts (a)-(d), also find the domain. f(x) = 5x + 3; g(x) = 3x - 7
(a) Find (f +g)(x).
(f + g)(x)=(Simplify your answer.)

I really don’t know how to do this like I really do need help if somebody could just please explain it in detail

Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x). To find the answers, all I have to do is apply the operations (plus, minus, times

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
