Penjelasan dengan langkah-langkah:
1)
Lim x² - x! + 7
x => 5
5² - 5! + 7
(5 × 5) - (5 × 4 × 3 × 2 × 1) + 7
25 - (20 × 6) + 7
25 - 120 + 7
-95 + 7
-88
2)
f(x) = 30x + 60x
f(20) = 30(20) + 60(20)
f(20) = 600 + 1200
f(20) = 1.800
3)
360 × 400
144.000

Lim x² - x! + 7
x → 5
5² - 5! + 7
= 5(5) - 5(4)(3)(2)(1) + 7
= 5(5) - 5(4)(3)(2) + 7
= 5(5) - 5(4)(6) + 7
= 5(5) - 5(24) + 7
= 25 - 120 + 7
= -95 + 7
= -88
f(x) = 30x + 60x
f(x) = 90x
f(20) = 90(20)
f(20) = 1.800
360 × 400
= 144.000
