Question

1. Oblicz w pamięci wartości liczbowe wyrażenia x² + 1 dla:
x=2
X = -1
x= 100
x = -5
x =0
x=1/2
​

Answer 1

Odpowiedź:

x² + 1

1) x = 2

2² + 1 = 4 + 1 = 5

2) x = -1

(-1)² + 1 = 1 + 1 = 2

3) x = 100

100² + 1 = 10000 + 1 = 10001

4) x = -5

(-5)² + 1 = 25 + 1 = 26

5) x = 0

0² + 1 = 1

6) x = 1/2

(1/2)² + 1 = 1/4 + 1 = 1
