find the value of g(7) for the function below

g(x)=7/8x-1/2
a:53/8
b:60/7
c:45/8
d:49/8

1 answer

To find g(7), we substitute 7 for x in the function g(x) and simplify:

g(7) = (7/8)(7) - 1/2 = 49/8 - 1/2.

To add fractions, we need to find a common denominator, which in this case is 8.

49/8 - 1/2 = 49/8 - 4/8 = 45/8.

Therefore, the value of g(7) is 45/8.

The correct option is c) 45/8.
