what di u get?

idk i dont understand how to do these

u know how to find f(3) ?

nope

its been a while since i did these and i forgot

to get f(3) put x=3 in f(x)

f(2) = (2)2 - 13 and g(2) = 2 + 5?

i mean three lol

f(3) = (3)2 - 13 and g(3) = 3 + 5?

yes that is right

now get an answer for each function
add your answers together

f(3) = 9 - 13 = f(3) = -4

g(3) = 3 + 5 = g(3) = 8

now what do i do???

f+g
-4+8

wait when i do f+g what do i do with the 3's??

-4+8=4

so the answer is 4??
