F(x) = 15x - 10 + x × 2xf(4) = ..

F(x) = 15x – 10 + x × 2xf(4) = ..

Jawaban:

$huge underline{ tt{color{b}Pertacolor{blue}nyaancolor{b}:}}$

Diketahui:

Suatu fungsi di nyatakan dengan f(x) = 15x – 10 + x × 2x

Ditanya:

Tentukan nilai dari f(4)

$huge underline{ tt{color{b}Cara : Penycolor{yellow}lesaiancolor{b}:}}$

Masukan Fungsi f = 4 pada fungsi 15x – 10 + x × 2x

$tt small f(x) = 15x - 10 + x × 2x$

$tt small f(4) = 15x - 10 + x × 2x$

$tt small f(4) = 15.4 - 10 + 4 × 2.4$

$tt small f(4) = 60 - 10 + ( 4 × 8 )$

$tt small f(4) = 60 - 10 + 32$

$tt small f(4) = 50 + 32$

$tt small f(4) = sf bold color{red} 82$

$huge underline{ tt{color{b}Kesimcolor{lime}pulancolor{b}:}}$

Jadi Nilai f(4) pada fungsi f(x) = 15x – 10 + x × 2x adalah $sf bold color{red} 82$

$huge - tt{ color{red}Xcolor{orange}hcolor{yellow}ycolor{lightgreen}o color{blue}1color{magenta}0color{grey}1} -$

Jawaban:

f(x) = 15x – 10 + x × 2x

f(4) = 15(4) – 10 + (4) × 2(4)

f(4) = (15 × 4) – 10 + 4 × (2 × 4)

f(4) = 60 – 10 + (4 × 8)

f(4) = 60 – 10 + 32

f(4) = 50 + 32

f(4) = 82
