Evaluate the function g(t)=5/2t-3/2, when t=3

a. 6
b. 9
c. 12
d. 13 1/2

Putting the value , so g = 15/2-3/2 = 12/2 = 6

so the answer is A !!

G(t) = 5/2 t - 3/2
t = 3
so we substitute the given into the function

g(3) = 5/2 (3) - 3/2
first multiply the 5/2 by 3
you get 15/2
then
g(3) = 15/2 - 3/2 
g(3) = 6

So A. 6

Hope this helps :)
