Qz.
f(x) = x × x - 10 × x
f(3)=?
f(4)=?![]()
f(x) = x × x - 10 × x
f(3)=?
f(4)=?
Penjelasan dengan langkah-langkah:
- ╰► Nilai f(3)
f(x) = x × x - 10 × x
f(3) = 3 × 3 - 10 × 3
f(3) = 9 - ( 10 × 3 )
f(3) = 9 - 30
f(3) = -21 ✔️
- ╰► Nilai f(4)
f(x) = x × x - 10 × x
f(4) = 4 × 4 - 10 × 4
f(4) = ( 4 × 4 ) - ( 10 × 4 )
f(4) = 16 - 40
f(4) = -24 ✔️

f(x) = x × x - 10 × x
____________
f(3) = 3 × 3 - 10 × 3
f(3) = (3 × 3) - (10 × 3)
f(3) = 9 - 30
f(3) = -21
____________
f(4) = 4 × 4 - 10 × 4
f(4) = (4 × 4) - (10 × 4)
f(4) = 16 - 40
f(4) = -24
