Question

Find the value of g7) for the function below.
g(x)= 7/8x -1/2

Answer 1

`g(7) = (45)/(8) \\ \: or \: \\ 5 (5)/(8)`

Explanation:

We would just apply the 7 in g(7) as all the x

g(x)= 7/8x - 1/2

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

`(7)/(8) * (7)/(1) = (49)/(8)`

Simplify

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

Multiply -1/2 by 4/4 to get the denominators the same

`(49)/(8) - (4)/(8) = (45)/(8)`

answer: g(7)=45/8

(simplified): g(7)=5 5/8
