f(x) = 5x × 4x - 2 + 1
f'(2) =.....

Note :..................​

Jawaban:

f(x) = 5x × 4x -2 + 1

f'(2) =...

f'(x) = 5x × 4x -2+1

f'(x) = 20x²-1

f'(x) = 40x-1

f'(2)= 40(2)-1

f'(2)= 80

Jawaban:

[tex] \sf f(x)=5x \times 4x - 2 + 1[/tex]

[tex] \: \: \: \: \: \: \: \sf \: \sf =20 {x}^{2} - 2 + 1[/tex]

[tex] \sf f'(x) =2 \: . \: 20 {x}^{(2 - 1)} \: \cancel{ - 0 + 0}[/tex]

[tex] \: \: \: \: \: \: \: \: \sf \: \sf =40x[/tex]

maka_________

[tex] \sf f'(2)= 40(2)[/tex]

[tex] \: \: \: \: \: \: \: \: \sf \: \sf =40 + 40[/tex]

[tex] \: \: \: \: \: \: \: \: \sf \: \sf =80[/tex]

kesimpulan

ʕっ•ᴥ•ʔっ[tex]\tiny \boxed{ \sf f'(2) \: dari \: f(x)=5x \times 4x - 2 + 1 \: adalah \: \blue{80} }[/tex]
