Question

F(a) = 2a - 1 g(a) = 4a - 1 Find f(a) + g(a)

Answer 1

Answer:

$f(a)+g(a)=6a-2$

Step-by-step explanation:

So we have the two functions:

$f(a)=2a-1\text{ and } g(a)=4a-1$

And we want to find f(a) + g(a).

So, substitute:

$f(a)+g(a)$

This is the same as:

$=(2a-1)+(4a-1)$

Combine like terms:

$=(2a+4a)+(-1-1)$

Add or subtract:

$=6a-2$

And we're done!
