Question

Diketahui suatu fungsi g dengan rumus g(×)=3×-1.Nilai fungsi g(×) untuk x=9per2 adalah...sekalian caranya a.10 1per2 b.12 1per2 c.15 1per2 d. 20 1per2

Answer 1

G(x) = 3x-1
x= 9/2
maka g(9/2) = 3(9/2) -1
= 27/2 - 2/2
25/2 (b) 12 1/2

Answer 2

G(x) = 3x - 1 ,
dgn nilai x ny 9/2.
Maka,
=> g(x) = 3x - 1
=> g(x) = 3.(9/2) - 1
=> g(x) = 27/2 - 1
=> g(x) = 27/2 - 2/2
=> g(x) = 25/2
=> g(x) = 12½ (b)
