dintentukan f(x) = x²-5n. jika f(5) =10 maka nilai n

[tex]f(5) = {5}^{2} - 5m \\ 10 = 25 - 5m \\ 5m = 25 - 10 \\ 5m = 15 \\ m = 3[/tex]
*nb ; variabel m Itu maksudnya n. mohon maaf saya ubah, karena touchscreen saya eror.

f(x) = x² - 5n
f(5) = 5² - 5n = 10
= 25 - 5n = 10
- 5n = 10 - 25
- 5n = -15
5n = 15
n = 15/5 = 3
