If f (x) = 7-3x and g (x) = 3x-7, what is the value of f (1) + g (1) ?

F (x) = 7-3x g (x) = 3x-7

First let's solve for f (1)

f (1) = 7-3 (1)

f (1) = 7-3

f (1) = 4 * we will save this for later

Let's now solve for g (1)

g (1) = 3 (1) - 7

g (1) = 3-7

g (1) = - 4

Now we can find f (1) + g (1)

f (1) = 4 and g (1) = - 4

4 + (-4) = 0
