hy ;-; masi ingat sy ciapa? :v

f(x) = 7x + 12x² - x × x + x/2
f(10) = ...
​

Penjelasan dengan langkah-langkah:

[tex]\tt{{{f(x) = 7x + 12x² - x × x + \frac{x}{2} }}}[/tex]

[tex]\tt{{{f(10) = 7(10) + 12(10²) - 10 × 10 + \frac{10}{2} }}}[/tex]

[tex]\tt{{{f(10) = 7(10) + 12(10×10) - 10 × 10 + \frac{10}{2} }}}[/tex]

[tex]\tt{{{f(10) = 7(10) + 12(100) - (10 × 10) + \frac{10}{2} }}}[/tex]

[tex]\tt{{{f(10) = 7(10) + 12(100) - 100 + \frac{10}{2} }}}[/tex]

[tex]\tt{{{f(10) = 7(10) + (12×100) - 100 + \frac{10}{2} }}}[/tex]

[tex]\tt{{{f(10) = 7(10) + 1.200 - 100 + \frac{10}{2} }}}[/tex]

[tex]\tt{{{f(10) = (7 × 10)+ 1.200 - 100 + \frac{10}{2} }}}[/tex]

[tex]\tt{{{f(10) = 70 + 1.200 - 100 + \frac{10}{2} }}}[/tex]

[tex]\tt{{{f(10) = 1.270- 100 + \frac{10}{2} }}}[/tex]

[tex]\tt{{{f(10) = 1.170 + \frac{10}{2} }}}[/tex]

[tex]\tt{{{f(10) = 1.170 + 5 }}}[/tex]

[tex]\tt\red{{{f(10) = 1.175}}}[/tex]

<< Penyelesaian >>

Diketahui :

• x = 10

Ditanya :

• f(x) = 7x + 12x² - x × x + x/2 = ??

Dijawab :

• f(x) = 7x + 12x² - x × x + x/2
• f(10) = 7(10) + 12(10²) - 10 x 10 + 10/2
• f(10) = ( 7 x 10 ) + ( 12 x 100 ) - ( 10 x 10 ) + 10/2
• f(10) = ( 70 ) + ( 1.200 ) - ( 100 ) + 10/2
• f(10) = 1.270 - 100 + 5
• f(10) = 1.170 + 5
• f(10) = 1.175
• f(10) = 1.175

<< Kesimpulan >>

• f(x) = 7x + 12x² - x × x + x/2  
• f(10) = 1.175
