Answer:
f(3)-g(3)= -13
Step-by-step explanation:
The problem is asking to obtain the numerical solution for the subtraction of two given function evaluated both in t=3.
We can do that by first, evaluating the point and then performing the subtraction.
If we evaluate t=3 in f(t)= -t +1 we have f(3)=-3+1=-2
If we now evaluate t=3 in g(t)=2t+5 we have g(3)=2*3+5=11
Now, f(3)-g(3)= -2 - 11 = -13
