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

$R_{h}$ = { $26 ≤ y ≤ 46, y in R$ }

_____________________________

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

$rm R_{h}$ = { $26 ≤ y ≤ 46, y in R$ }

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