Question

h(t)=t+2
g(t)=2t^2+3
Find h(-7) +g(-7)

Answer 1

-7(h+g)

Answer 2

nah its not like that....

Answer 3

substitute t=-7 into both of h(t) and g(t) then do h(t=-7)+g(t=-7)

Answer 4

h(-7)=-5, g(-7)=2(49)+3
h(-7)+g(-7)=-5+101=96

Answer 5

yeah .. i know that.. but would that equation look like this if i were supossed to do that?
h(t)=t+2
g(t)=2t^2+3
Find (h+g)(-7) <------

Answer 6

yes cause all dependent variables are depend on only one independent variables, t
so you can sum both of function together, what if h(-3) and g(-5) could you ??
