Question

Diket. h(x)=3x-b. Jika h(3) =4, hitung nilai dari h(-1)+h(6) !! .. Tlong jwab y

Answer 1

Cari dulu nilai b-nya
h(3) = 4
3(3) - b = 4
9 - b = 4
b = 5

substitusikan b
h(x) = 3x - b
h(x) = 3x - 5

h(-1) = 3(-1) - 5
h(-1) = -3 - 5
h(-1) = -8

h(6) = 3(6) - 5
h(6) = 18 - 5
h(6) = 13

h(-1) + h(6)
= -8 + 13
= 5

semoga benar ya... ;-)
