Diketahui rumus fungsi h(a) = 5a + 1, jika domain fungsi D = { 5 ≤ a ≤ 9 , a € Real } maka tentukan daerah hasil fungsi/range tersebut !

Fungsi

 R_{h} = { 26 ≤ y ≤ 46, y in R }

_____________________________

Utk nilai a = 5

 rm h(a) = 5a + 1

 rm h(5) = 5(5) + 1

 rm h(5) = 26

Utk nilai a = 9

 rm h(a) = 5a + 1

 rm h(9) = 5(9) + 1

 rm h(9) = 46

Range fungsi

 rm R_{h} = { 26 ≤ y ≤ 46, y in R }

PEMBAHASAAN :

Nilai A (Nilai A = 5)

h(5) = 5a + 1

h(5) = 5(5) + 1

h(5) = 25 + 1

h(5) = boxed{orange{bf{26}}}

Nilai B (Nilai B = 9)

h(9) = 5a + 1

h(9) = 5(9) + 1

h(9) = 45 + 1

h(9) = boxed{orange{bf{46}}}

Range

Rh = {A ≤ y ≤ B. y ∈ R}

Rh = boxed{orange{bf{26~≤~y~≤~46.~y~∈~R}}}
